+Subject: treewide: Remove uninitialized_var() usage
+
+From: Kees Cook <keescook@chromium.org>
+
+commit 3f649ab728cda8038259d8f14492fe400fbab911 upstream.
+
+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.
