Merge tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux

Pull 'fallthrough' keyword conversion from Gustavo A. R. Silva:
"A tree-wide patch that replaces tons (2484) of /* fall through */
comments, and its variants, with the new pseudo-keyword macro
fallthrough[1]. Also, remove unnecessary fall-through markings when it
is the case.

There are currently 1167 intances of this fallthrough pseudo-keyword
macro in mainline (5.9-rc2), that have been introduced over the last
couple of development cycles:

$ git grep -nw 'fallthrough;' | wc -l
1167

The global adoption of the fallthrough pseudo-keyword is something
certain to happen; so, better sooner than later. :) This will also
save everybody's time and thousands of lines of unnecessarily
repetitive changelog text.

After applying this patch on top of 5.9-rc2, we'll have a total of
3651 instances of this macro:

$ git grep -nw 'fallthrough;' | wc -l
3651

This treewide patch doesn't address ALL fall-through markings in all
subsystems at once because I have previously sent out patches for some
of such subsystems separately, and I will follow up on them; however,
this definitely contributes most of the work needed to replace all the
fall-through markings with the fallthrough pseudo-keyword macro in the
whole codebase.

I have build-tested this patch on 10 different architectures: x86_64,
i386, arm64, powerpc, s390, sparc64, sh, m68k, powerpc64 and alpha
(allyesconfig for all of them). This is in linux-next already and
kernel test robot has also helped me to successfully build-test early
versions of this patch[2][3][4][5]"

treewide: Remove uninitialized_var() usage

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.
