From a8f28cfad8cd44d7c34b166d0e5ace1125dbee1f Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Mon, 8 Oct 2012 22:06:30 +0200 Subject: regmap: silence GCC warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
