Currently if the call to of_resolve_phandles fails then then ovcs
is not kfree'd on the error exit path. Rather than try and make
the clean up exit path more convoluted, fix this by just kfree'ing
ovcs at the point of error detection and exit via the same exit
path.

f2fs_chksum and f2fs_crc32 use the same 'crc32' crypto engine, also
their implementation are almost the same, except with different
shash description context.
Introduce __f2fs_crc32 to wrap the common codes, and reuse it in
f2fs_chksum and f2fs_crc32.

The cryptd_max_cpu_qlen module parameter is local to the source and does
not need to be in global scope, so make it static.
Cleans up sparse warning:
crypto/cryptd.c:35:14: warning: symbol 'cryptd_max_cpu_qlen' was not
declared. Should it be static?

After the last dist upgrade my system (I use Debian unstable amd64), was
encountered a problem, that begined from the kernel 4.13 and probably concerns
the wmi module. Kernel version 4.12 and lower is ok.
I have a HP ProBook 6475b notebook. When I plug-in it in the 'HP 230W Advanced

A typical code fragment was copied across many dvb-frontend drivers and
causes large stack frames when built with with CONFIG_KASAN on gcc-5/6/7:
drivers/media/dvb-frontends/cxd2841er.c:3225:1: error: the frame size of 3992
bytes is larger than 3072 bytes [-Werror=frame-larger-than=]
drivers/medi
With CONFIG_KASAN, we get an overly long stack frame due to inlining
the register access functions:
drivers/media/tuners/r820t.c: In function 'generic_set_freq.isra.7':
drivers/media/tuners/r820t.c:1334:1: error: the frame size of 2880 bytes is
