dma_request_chan() assumes both @dev and @name are valid, but neither is
checked before use.
dev is dereferenced immediately via dev_fwnode(), which accesses
dev->of_node or dev->fwnode without checking for NULL. Likewise, if name is
NULL and the OF/ACPI lookup does not succeed, the legacy filter-map path
eventually passes it to strcmp(), resulting in a NULL pointer dereference.
These are caller bugs rather than normal lookup failures, so add a
WARN_ON() at function entry to catch invalid arguments early during
development instead of crashing later.
No functional change for valid callers.

rtw_get_wps_ie() iterates over IE data from network frames without
validating that the IE header and payload fit within the remaining
buffer before reading them. Specifically:
- in_ie[cnt + 1] is read without checking cnt + 1 < in_len
- memcmp(&in_ie[cnt + 2], ...) accesses cnt + 2 without bounds check
- in_ie[cnt + 1] is used as length without verifying payload fits
Add bounds checks at the top of the loop body to break early if fewer
than 2 bytes remain for the IE header, or if the declared payload
extends past the end of the buffer. Also require at least 4 bytes of
payload before comparing the WPS OUI.

rtw_get_chan_type() maps the driver's channel offset to nl80211 channel
types the wrong way around.
In this driver HAL_PRIME_CHNL_OFFSET_LOWER means the primary channel is
the lower 20 MHz half of the 40 MHz pair, i.e. the secondary channel is
above the primary one: rtw_get_center_ch() computes the center channel
as "channel + 2" for OFFSET_LOWER, and bwmode_update_check() sets
OFFSET_LOWER when the AP's HT operation IE announces SCA (secondary
channel above). In nl80211 terms that is NL80211_CHAN_HT40PLUS, not
HT40MINUS.
Because of the inversion, cfg80211_rtw_get_channel() reports an HT40+
association as HT40-. For an HT40+ AP on a low channel (e.g. channel 3)
the resulting chandef spans below the 2.4 GHz band edge and is invalid,
so the regulatory core tears the connection down 60 seconds
(REG_ENFORCE_GRACE_MS) after the AP's country IE triggers a regdomain
change: reg_check_chans_work() considers the reported chandef unusable
and calls cfg80211_leave(). The supplicant then reconnects, the country
IE changes the regdomain again, and the cycle repeats, causing a
disconnect/reconnect loop every ~65 seconds for as long as the link is
up.
Observed on a TECLAST X80 Power tablet (RTL8723BS) associated to an
HT40+ AP on channel 3 with a KR country IE; a kprobe trace showed
cfg80211_disconnect() being invoked from reg_check_chans_work(). With
the mapping fixed, "iw dev wlan0 info" reports the correct
"width: 40 MHz, center1: 2432 MHz" and the periodic disconnects stop.

Replace the open-coded platform_get_resource() plus devm_ioremap()
sequence with devm_platform_ioremap_resource(), which fetches the
resource, requests the region and maps it in one call. Switch the error
check to IS_ERR()/PTR_ERR() and drop the now-unused struct resource
pointer.
The raideng node has a single reg region (0x320000, 0x10000); the
job-queue/ring children are separate OF devices probed independently, so
the region reservation added by devm_ioremap_resource() is exclusive and
does not introduce overlap failures.

The fsl_re_ctrl and fsl_re_chan_cfg structures describe memory-mapped
RAID Engine registers accessed only via ioread32be()/iowrite32be(), yet
the pointers to them (re_regs in struct fsl_re_drv_private, and jrregs
in struct fsl_re_chan) were not __iomem-qualified, so sparse emitted
"different address spaces" warnings for every register access.
Store both MMIO bases as a plain void __iomem * and derive jrregs with
void __iomem * arithmetic from re_regs, rather than carrying typed
register struct pointers through the driver. Each function that touches
the registers introduces a local typed pointer (struct fsl_re_ctrl
__iomem *ctrl) and uses ->field, which is the idiomatic kernel pattern
and keeps the registers' __iomem qualification intact.

The descriptor structs (fsl_re_cmpnd_frame / fsl_re_hw_desc) are
in-memory but their fields are __be32, because the structures are handed
to the device as big-endian. The driver stored CPU-endian u32 values
into them directly, which is both wrong (the engine would see
byte-swapped lengths/addresses) and flagged by sparse as a base-type
mismatch.
Wrap those stores in cpu_to_be32() so the values are little->big

issue_beacon(), issue_probersp() and issue_asocrsp() obtain a management
xmit_frame together with its xmit_buf from the driver's fixed-size
management-TX pools via alloc_mgtxmitframe(). On the normal path the frame
is handed to dump_mgntframe(), which transfers ownership and eventually
returns both objects to their pools (the frame and, for beacons, the buf
in rtl8723bs_mgnt_xmit(); other bufs via the pending-xmitbuf/TX-completion
path).
Several error/edge paths return early after a successful
alloc_mgtxmitframe() but before dump_mgntframe(), so ownership is never
transferred and neither object is freed:
- issue_beacon(): beacon larger than 512 bytes
- issue_probersp(): cur_network->ie_length > MAX_IE_SZ
- issue_probersp(): kzalloc() of the SSID scratch buffer fails
- issue_asocrsp(): pkt_type is neither ASSOCRSP nor REASSOCRSP
Because alloc_mgtxmitframe() removes the frame and buf from their free
lists (list_del_init) without placing them on any pending list, an
orphaned pair is on no list and referenced by nobody, so it is only
reclaimed at driver teardown. Repeated hits progressively exhaust the
management-TX pools until alloc_mgtxmitframe() returns NULL and the
interface can no longer send beacons or probe/assoc responses.
Free the frame and buffer on these paths, matching the existing correct
error handling in issue_assocreq().

nvec_power_probe() calls devm_kzalloc() with GFP_NOWAIT, which
disables direct reclaim and is meant for atomic context. probe()
runs in normal process context and may sleep, so this needlessly
risks a spurious -ENOMEM under memory pressure instead of just
waiting for reclaim like every other probe() allocation does.
nvec.c's own tegra_nvec_probe() already uses GFP_KERNEL for the
identical pattern, confirming this is an oversight, not intentional.

The value 'BT_RTL8723B' is written to this field, but it is not used in
any other way, so remove it.

A value is written to this field, but it is never used. Remove it, along
with the associated functions and macros, to simplify the code.

As per 'Designware Cores PCI Express Controller Databook',
Section 7.1 - Overview, HDMA supports 64 Read and 64 Write
channels. Current controller driver supports up to 8 read and
write channels only. In order to utilize all the channels the
controller driver need to have the channel related structs
and variables as per the number of channels supported by IP.
Following changes are made to enable 64 Read / 64 Write
channel support:
o Defined HDMA specific macros to reflect the channel count.
o The count of ll_regions and dt_regions in dw_edma_chip and
dw_edma_pcie_data shall be in accordance to number of read
and write channels.
o In dw_edma_probe() configure the channels as per the channels
of the IP used.
o Changed mask types to u64 for higher channel counts.

udf_symlink_filler() can enter udf_pc_to_char() with a partial pathComponent header.
Validate that enough input remains for a complete pathComponent header
before accessing it. Reject malformed symlink data that would otherwise
make udf_pc_to_char() perform an out-of-bounds read.

Add a per-port debugfs boolean "tx_timeout_skip_reset" that, when
enabled, makes mana_tx_timeout() log the TX timeout and return without
queueing the per-port detach/attach recovery work.
This is a debug-only aid for bringup and qualification: skipping the
recovery reset keeps the device and queue state intact so a TX timeout
can be correlated with hardware telemetry. The knob defaults to false,
so production recovery behaviour is unchanged.
