3.5.7.22 -stable review patch. If anyone has any objections, please let me know.

From: Paul Bolle <pebolle@tiscali.nl>
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.
