Hi Mark,
I am getting compilation warning while compiling v3.8
commit 19f949f52599ba7c3f67a5897ac6be14bfcb1200 Author: Linus Torvalds torvalds@linux-foundation.org Date: Mon Feb 18 15:58:34 2013 -0800
Linux 3.8
Warning:
CC drivers/base/regmap/regmap-debugfs.o drivers/base/regmap/regmap-debugfs.c: In function ‘regmap_read_debugfs’: drivers/base/regmap/regmap-debugfs.c:180:9: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
I am unable to understand why this warning is coming and that too on line 180 (as that doesn't use this variable). I can't see how this variable is used uninitialized.
Toolchain i used:
arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.7-2012.12-20121214 - Linaro GCC 2012.12) 4.7.3 20121205 (prerelease)
