Module aliases are used by userspace to identify the correct module to

Use the helper macro MODULE_DEVICE_TABLE(rpmsg) to export the correct
supported IDs. And while here, to keep backwards compatibility we also add
the other ID "rpmsg_chrdev" so that it is also still exported as an alias.
This has the side benefit of adding support for some legacy firmware

this driver before it was upstreamed (as reflected by the module alias).

GPD devices originally used BMI160 sensors with the "BMI0160" PNP ID.
When they switched to BMI260 sensors in newer hardware, they reused
the existing Windows driver which accepts both "BMI0160" and "BMI0260"
IDs. Consequently, they kept "BMI0160" in DSDT tables for new BMI260
devices, causing driver mismatches in Linux.
1. GPD updated BIOS v0.40+[1] for newer devices to report "BMI0260" for
BMI260 sensors to avoid loading the bmi160 driver on Linux. While this
isn't Bosch's VID;
2. Bosch's official Windows driver uses "BMI0260" as a compatible ID
3. We're seeing real devices shipping with "BMI0260" in DSDT

At least for panel-bridges, the atomic_enable call is defined as being
called right after the preceding element in the display pipe is enabled.
It is also stated that "The bridge can assume that the display pipe (i.e.
clocks and timing signals) feeding it is running when this callback is
called"
This means the DSI controller driving this display would have already
switched over to video-mode from command mode and thus dcs functions
should not be called anymore at this point.
This caused a non-working display for me, when trying to enable
the rk3576 dsi controller using a display using this controller.
Therefore move the display_on/off calls the more appropriate
prepare/unprepare callbacks.

idpf has a limit on number of scatter-gather frags

Currently, idpf_tx_start() checks if the limit is hit
and forces a linearization of the whole packet.
This requires high order allocations that can fail
under memory pressure. A full size BIG-TCP packet
would require order-7 alocation on x86_64 :/
We can move the check earlier from idpf_features_check()
for TSO packets, to force GSO in this case, removing the
cost of a big copy.
This means that a linearization will eventually happen
with sizes smaller than one MSS.
__idpf_chk_linearize() is renamed to idpf_chk_tso_segment()

The stmmac_rx function would previously set skb->ip_summed to
CHECKSUM_UNNECESSARY if hardware checksum offload (CoE) was enabled
and the packet was of a known IP ethertype.
However, this logic failed to check if the hardware had actually
reported a checksum error. The hardware status, indicating a header or
payload checksum failure, was being ignored at this stage. This could
cause corrupt packets to be passed up the network stack as valid.
This patch corrects the logic by checking the `csum_none` status flag,
which is set when the hardware reports a checksum error. If this flag
is set, skb->ip_summed is now correctly set to CHECKSUM_NONE,
ensuring the kernel's network stack will perform its own validation and
properly handle the corrupt packet.

[ Upstream commit b0ac6d3b56 ]
When removing a nexthop, commit
90f33bffa3 ("nexthops: don't modify published nexthop groups") added a
call to synchronize_rcu() (later changed to _net()) to make sure
everyone sees the new nexthop-group before the rtnl-lock is released.
When one wants to delete a large number of groups and nexthops, it is
fastest to first flush the groups (ip nexthop flush groups) and then
flush the nexthops themselves (ip -6 nexthop flush). As that way the
groups don't need to be rebalanced.
However, `ip -6 nexthop flush` will still take a long time if there is
a very large number of nexthops because of the call to
synchronize_net(). Now, if there are no more groups, there is no point
in calling synchronize_net(). So, let's skip that entirely by checking
if nh->grp_list is empty.
This gives us a nice speedup:

[ Upstream commit 1ba0fb42aa ]
misc_open() may request module for miscdevice with dynamic minor, which
is meaningless since:
- The dynamic minor allocated is unknown in advance without registering
miscdevice firstly.
- Macro MODULE_ALIAS_MISCDEV() is not applicable for dynamic minor.
Fix by only requesting module for miscdevice with fixed minor.

[ Upstream commit 52e2bb5ff0 ]
For miscdevice who wants dynamic minor, it may fail to be registered again
without reinitialization after being de-registered, which is illustrated
by kunit test case miscdev_test_dynamic_reentry() newly added.
There is a real case found by cascardo when a part of minor range were
contained by range [0, 255):
1) wmi/dell-smbios registered minor 122, and acpi_thermal_rel registered
minor 123
2) unbind "int3400 thermal" driver from its device, this will de-register
acpi_thermal_rel
3) rmmod then insmod dell_smbios again, now wmi/dell-smbios is using minor
123
4) bind the device to "int3400 thermal" driver again, acpi_thermal_rel
fails to register.
Some drivers may reuse the miscdevice structure after they are deregistered
If the intention is to allocate a dynamic minor, if the minor number is not
reset to MISC_DYNAMIC_MINOR before calling misc_register(), it will try to
register a previously dynamically allocated minor number, which may have
been registered by a different driver.
One such case is the acpi_thermal_rel misc device, registered by the
int3400 thermal driver. If the device is unbound from the driver and later
bound, if there was another dynamic misc device registered in between, it
would fail to register the acpi_thermal_rel misc device. Other drivers
behave similarly.
Actually, this kind of issue is prone to happen if APIs
misc_register()/misc_deregister() are invoked by driver's
probe()/remove() separately.
Instead of fixing all the drivers, just reset the minor member to
MISC_DYNAMIC_MINOR in misc_deregister() in case it was a dynamically
allocated minor number, as error handling of misc_register() does.

Mark dm error as DM_TARGET_PASSES_INTEGRITY so that it can be stacked on
top of PI capable devices. The claim is strictly speaking as lie as dm
error fails all I/O and doesn't pass anything on, but doing the same for
integrity I/O work just fine :)
This helps to make about two dozen xfstests test cases pass on PI capable
devices.

In WoWLAN net-detect mode, the firmware periodically performs scans

unnecessary C2H events cause firmware watchdog timeout, leading
to unexpected wakeups and SER 0x2599 on 8922AE.

On some Qualcomm platforms such as QCS6490-RB3Gen2, the multiple
WSA8830/WSA8835 speaker amplifiers share a common reset (shutdown) GPIO.
To handle such scenario, use the reset controller framework and its
"reset-gpio" driver to handle such case. This allows proper handling
of all WSA883x speaker amplifiers on QCS6490-RB3Gen2 board.

use-after-free errors. Duplicate the name to avoid that.
At the same time, update the order of operations - since commit
cee28113db ("ASoC: dmaengine_pcm: Allow passing component name via
config") the framework does not override component->name if set before
invoking the initializer.

This fix is already present in f_ecm.c and was never
propagated to f_ncm.c
When creating multiple NCM ethernet devices
on a composite usb gadget device
each MAC address on the HOST side will be identical.
Having the same MAC on different network interfaces is bad.
This fix updates the MAC address inside the
ncm_strings_defs global during the ncm_bind call.
This ensures each device has a unique MAC.
In f_ecm.c ecm_string_defs is updated in the same way.
The defunct MAC assignment in ncm_alloc has been removed.

ADC calibration might fail because of the noise on reference voltage.
To avoid calibration fail, need to meet the following requirement:
ADC reference voltage Noise < 1.8V * 1/2^ENOB
For the case which the ADC reference voltage on board do not meet
the requirement, still load the calibrated values, so ADC can also
work but maybe not that accurate.
