While there are issues related to object lifetime management, unregister
the media device first, followed immediately by other device nodes when
the driver is being unbound. Only then the resources needed by the driver
may be released. This is slightly safer.

Patch ad608fbcf166 changed how events were subscribed to address an issue
elsewhere. As a side effect of that change, the "add" callback was called
before the event subscription was added to the list of subscribed events,
causing the first event queued by the add callback (and possibly other
events arriving soon afterwards) to be lost.
Fix this by adding the subscription to the list before calling the "add"
callback, and clean up afterwards if that fails.

Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.
This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.
This has been verified and tested by Maarten and the change is working
as expecpted.
v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.
v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.
v4: Added support for Limited Range Color Handling
v5: Fixed Matt and Maarten's review comments.
v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.
v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.
v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.
v9: Fixed Ville's review comments.

Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.
v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.
v3: Removed a redundant 3rd Pipe register definition and
simplified the equally spaced register definition by adding an
offset as per Matt's comment.

This reverts commit d27dfa13b9f77ae7e6ed09d70a0426ed26c1a8f9.
Unfortunately, this patch needs to be reverted. We need the full sync
barrier and not the limited barrier provided by using an ordered store.
The sync ensures that all accesses and cache purge instructions that
follow the sync are performed after all such instructions prior the sync
instruction have completed executing.
The patch breaks the rwlock implementation in glibc. This caused the
test-lock application in the libprelude testsuite to hang. With the
change reverted, the test runs correctly and the libprelude package
builds successfully.

Due to what appears to be a copy/paste error, the opening ENTRY()
of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead,
the one for cpu_v7_smc_switch_mm() is duplicated.
Given that it is ENDPROC() that emits the Thumb annotation, the
cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a
Thumb2 kernel, resulting in the following splat:

structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

Current check for the last extra TRB for zero and unaligned transfers
does not account for isoc OUT. The last TRB of the Buffer Descriptor for
isoc OUT transfers will be retired with HWO=0. As a result, we won't
return early. The req->remaining will be updated to include the BUFSIZ
count of the extra TRB, and the actual number of transferred bytes
calculation will be wrong.

Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.
To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels. Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.

When iptables command is executed, ip_{set/get}sockopt() try to upload
bpfilter.ko if bpfilter is enabled. if it couldn't find bpfilter.ko,
command is failed.
bpfilter.ko is generated if CONFIG_BPFILTER_UMH is enabled.
ip_{set/get}sockopt() only checks CONFIG_BPFILTER.
So that if CONFIG_BPFILTER is enabled and CONFIG_BPFILTER_UMH is disabled,
iptables command is always failed.
test config:
CONFIG_BPFILTER=y
# CONFIG_BPFILTER_UMH is not set
test command:
%iptables -L
iptables: No chain/target/match by that name.

There is no reason to discard using source link local address when
remote netconsole IPv6 address is set to be link local one.

For non-zero return from dumpit() we should break the loop
in rtnl_dump_all() and return the result. Otherwise, e.g.,
we could get the memory leak in inet6_dump_fib() [1]. The
pointer to the allocated struct fib6_walker there (saved
in cb->args) can be lost, reset on the next iteration.
Fix it by partially restoring the previous behavior before
commit c63586dc9b3e ("net: rtnl_dump_all needs to propagate
error from dumpit function"). The returned error from
dumpit() is still passed further.

Commit 5390a8df769e ("mtd: spi-nor: add support to non-uniform SFDP SPI
NOR flash memories") removed the 'nor->addr_width = 0;' statement when
spi_nor_parse_sfdp() returns an error, thus leaving ->addr_width in an
undefined state which can cause trouble when spi_nor_scan() checks its
value.

We return 0 unconditionally in 'cqspi_direct_read_execute()'.
However, 'ret' is set to some error codes in several error handling

Xtensa ABI requires stack alignment to be at least 16. In noMMU
configuration ARCH_SLAB_MINALIGN is used to align stack. Make it at
least 16.
This fixes the following runtime error in noMMU configuration, caused by
interaction between insufficiently aligned stack and alloca function,
that results in corruption of on-stack variable in the libc function
glob:

For allocating XArrays, it makes sense to distinguish beteen erasing an
entry and storing NULL. Storing NULL keeps the index allocated with a
NULL pointer associated with it while xa_erase() frees the index. Some
existing IDR users rely on this ability.
