Subject: [PATCH] regmap: silence GCC warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

commit a8f28cfad8cd44d7c34b166d0e5ace1125dbee1f upstream.

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.
