[Query]: Regmap v3.8: Compilation Warning: regmap_read_debugfs()

[Viresh Kumar]

Hi Mark,

I am getting compilation warning while compiling v3.8

commit 19f949f52599ba7c3f67a5897ac6be14bfcb1200
Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
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)
