Subject: regmap: silence GCC warning
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a8f28cfad8cd44d7c34b166d0e5ace1125dbee1f;p=linux-beck.git

regmap: silence GCC warning

Building regmap.o triggers this GCC warning:
    drivers/base/regmap/regmap.c: In function ‘regmap_raw_read’:
    drivers/base/regmap/regmap.c:1172:6: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]

Long story short: Jakub Jelinek pointed out that there is a type
mismatch between 'num' in regmap_volatile_range() and 'val_count' in
regmap_raw_read(). And indeed, converting 'num' to the type of
'val_count' (ie, size_t) makes this warning go away.
