From 5ade39358f0244a0672860766eed92e8c908b805 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 9 Apr 2012 22:32:49 +0800 Subject: [PATCH] regulator: twl-regulator: Simplify the code matching regulator id This patch makes the code easier to read. Also add checking the case when no desc id is matched. This is required because if no desc id is matched, the poiner info is pointed to twl_of_match[i].data which may be not NULL. Checking info is NULL or not latter does not catch the error.
