[PATCH] drivers: staging: iio: adc: fix uninitialized use
From: Chris Forbes
Date: Sat Jul 02 2011 - 21:47:21 EST
Fixed an uninitialized variable access. In the first two error paths in
max1363_probe(), 'st' is not yet initialized, but its 'reg' member is
accessed anyway. This would most likely crash.
The intended value for st->reg *is* available at that point in 'reg',
so just use that directly.
