media: atmel: atmel-isc-base: fix bytesperline value for planar formats

The bytesperline field of the pixfmt should be only for the first plane
in case of planar formats like YUV420 or YUV422.
The bytesperline is used by the driver to compute the framesize.
We have to report a different bpp (bytes per pixel) to v4l2 in bytesperline
than the actual bpp.
For example for YUV420, the real bpp is 12, but the first plane has only
8 bpp. Thus we report a bytesperline 8*width instead of 12*width.
However, for real framezise we have to compute 12*width*height.
Hence added a new variable to hold this information and to correctly
compute the frame size.

The driver allocates and registers two platform device structures during

This results in a use-after-free on driver unbind as the device

Fix this by adding the missing deregistration calls to the remove()

Note that the platform device structures must be freed using a proper

Pull ftrace fix from Steven Rostedt:
 "Fix s390 breakage from sorting mcount tables.

  The latest merge of the tracing tree sorts the mcount table at build
  time. But s390 appears to do things differently (like always) and
  replaces the sorted table back to the original unsorted one. As the
  ftrace algorithm depends on it being sorted, bad things happen when it
  is not, and s390 experienced those bad things.

  Add a new config to tell the boot if the mcount table is sorted or
  not, and allow s390 to opt out of it"

* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  ftrace: Fix assuming build time sort works for s390

ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

perf evsel: Override attr->sample_period for non-libpfm4 events

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.

Before said patch:

  perf record -c 10000 -e arm_spe_0// -- sleep 1

Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

This patch restores the previous behaviour for non-libpfm4 events.

perf script: Fix printing 'phys_addr' failure issue

Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.

Now referring to 'addr', use evsel__do_check_stype() to check the type.

Before:

  # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
  # perf script -F pid,tid,addr,phys_addr
  Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.

After:

  # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3

certs: Fix build error when CONFIG_MODULE_SIG_KEY is empty

Since b8c96a6b466c ("certs: simplify $(srctree)/ handling and remove
config_filename macro"), when CONFIG_MODULE_SIG_KEY is empty,
signing_key.x509 fails to build:

    CERT    certs/signing_key.x509
  Usage: extract-cert <source> <dest>
  make[1]: *** [certs/Makefile:78: certs/signing_key.x509] Error 2
  make: *** [Makefile:1831: certs] Error 2

Pass "" to the first argument of extract-cert to fix the build error.

certs: Fix build error when CONFIG_MODULE_SIG_KEY is PKCS#11 URI

When CONFIG_MODULE_SIG_KEY is PKCS#11 URL (pkcs11:*), signing_key.x509
fails to build:

  certs/Makefile:77: *** target pattern contains no '%'.  Stop.

Due to the typo, $(X509_DEP) contains a colon.

Fix it.

Revert "Makefile: Do not quote value for CONFIG_CC_IMPLICIT_FALLTHROUGH"

This reverts commit cd8c917a56f20f48748dd43d9ae3caff51d5b987.

Commit 129ab0d2d9f3 ("kbuild: do not quote string values in
include/config/auto.conf") provided the final solution.

Now reverting the temporary workaround.

usr/include/Makefile: add linux/nfc.h to the compile-test coverage

As linux/nfc.h userspace compilation was finally fixed by commits
79b69a83705e ("nfc: uapi: use kernel size_t to fix user-space builds")
and 7175f02c4e5f ("uapi: fix linux/nfc.h userspace compilation errors"),
there is no need to keep the compile-test exception for it in
usr/include/Makefile.
