8b0d31532e ASoC: TWL4030: Fix for digital loopback gain range
When the gain is configured using dB value it was
not possible to use -24dB since the loopback got
muted instead of -24dB.

02d37bed18 firewire: core: integrate software-forced bus resets with bus management
Bus resets which are triggered
  - by the kernel drivers after updates of the local nodes' config ROM,
  - by userspace software via ioctl
shall be deferred until after >=2 seconds after the last bus reset.

If multiple modifications of the local nodes' config ROM happen in a row,
only a single bus reset should happen after them.

When the local node's link goes from inactive to active or vice versa,
and at the two occasions of bus resets mentioned above --- and if the
current gap count differs from 63 --- the bus reset should be preceded
by a PHY configuration packet that reaffirms the gap count.  Otherwise a
bus manager would have to reset the bus again right after that.

This is necessary to promote bus stability, e.g. leave grace periods for
allocations and reallocations of isochronous channels and bandwidth,
SBP-2 reconnections etc.; see IEEE 1394 clause 8.2.1.

This change implements all of the above by moving bus reset initiation
into a delayed work (except for bus resets which are triggered by the
bus manager workqueue job and are performed there immediately).  It
comes with a necessary addition to the card driver methods that allows
to get the current gap count from PHY registers.

8b4f70ba49 firewire: cdev: fix fw_cdev_event_bus_reset emission after local config ROM changes
When a descriptor was added or removed to the local node's config ROM,
userspace clients which had a local node's /dev/fw* open did not receive
any fw_cdev_event_bus_reset for poll()/read() consumption.

The cause was that the core-device.c facility which re-reads the config
ROM of the bus reset initiator node missed to call the fw_device update
function.  The fw_units are destroyed and newly added, but their parent
stays and needs to be updated.

eb5b35a560 firewire: core: ensure some userspace API constants match corresponding kernel API constants
The FW_ISO_ constants of the in-kernel API of firewire-core and
FW_CDEV_ISO_ constants of the userspace API of firewire-core have
nothing to do with each other --- except that the core-cdev.c
implementation relies on them having the same values.

Hence put some compile-time assertions into core-cdev.c.  It's lame but
I prefer it over including the userspace API header into the kernelspace
API header and defining kernelspace API constants from userspace API
constants.  Nor do I want to expose the kernelspace constants in one of
the two firewire headers that are exported to userland since this only
concerns the core-cdev.c implementation.

656b7afd40 firewire: core: fix fw_send_request kerneldoc comment

Reported-by: Ben Gamari <bgamari.foss@gmail.com>

While we are at fixing the whole documentation of fw_send_request(),
also improve the rest of firewire-core's kerneldoc comments:
  - Add a bit of text concerning fw_run_transaction()'s call parameters.
  - Append () to function names and tab-align parameter descriptions as
    suggested by the example in Documentation/kernel-doc-nano-HOWTO.txt.
  - Remove kerneldoc markers from comments on static functions.
  - Remove outdated parameter descriptions at build_tree().

a8e93f3dcc firewire: cdev: check write quadlet request length to avoid buffer overflow
Check that the data length of a write quadlet request actually is large
enough for a quadlet.  Otherwise, fw_fill_request could access the four
bytes after the end of the outbound_transaction_event structure.

Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

Modification of Clemens' change:  Consolidate the check into
init_request() which is used by the affected ioctl_send_request() and
ioctl_send_broadcast_request() and the unaffected
ioctl_send_stream_packet(), to save a few lines of code.

Note, since struct outbound_transaction_event *e is slab-allocated, such
an out-of-bounds access won't hit unallocated memory but may result in a
(virtually impossible to exploit) information disclosure.

6fb4374f6b UBIFS: fix GC LEB recovery
UBIFS tries to alway have an LEB reserved for GC, and stores it
in c->gc_lnum. Besides, there is GC head which points to the current
GC head LEB.

In case of an unclean power cut, what may happen is that the GC head
was switched to the reserved GC LEB (c->gc_lnum), but a new reserved
GC LEB was not created yet. So, after an unclean reboot we may have
no reserved GC LEB, and we need to find a new LEB for this.

To do this, we find a dirty LEB which can fit the current GC head,
move the data, unmap this dirty LEB, and it becomes our reserved GC
LEB.

However, if we cannot find a dirty enough LEB, we return failure,
which is wrong, because we still can have free LEBs to use for
the reserved GC LEB. This patch fixes the issue.

This patch also fixes few typos in comments, which were spotted by
aspell.

Note, this patch fixes a real issue

15fd0cd9a2 net: autoconvert trivial BKL users to private mutex
All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

41090eb424 drm/nouveau: fix pcirom vbios shadow breakage from acpi rom patch
On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.

This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets.  The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.

112d20ad5c drm/nouveau: Disable PROM access on init.
On older cards (<nv17) scanout gets blocked when the ROM is being
accessed. PROM access usually comes out enabled from suspend, switch
it off.

e88efe056d drm/nouveau: initialise display before enabling interrupts
In some situations it's possible we can receive a spurious hotplug IRQ
before we're ready to handle it, leading to an oops.

Calling the display init before enabling interrupts should clear any
pending IRQs on the GPU and prevent this from happening.

271f29e7b5 drm/nv50: move dp_set_tmds() function to happen in the last display irq
It seems on some chipsets that doing this from the 0x20 handler causes the
display engine to not ever signal the final 0x40 stage.
