From 77fa44d0e10711e899788c58fe53f8f7b18c7f67 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 12 May 2011 13:47:50 +0800 Subject: [PATCH] regulator: Fix desc_id for tps65023/6507x/65910 The desc_id variable should not be a static variable. The rest of the code assumes the desc_id must less than TPSxxxxx_NUM_REGULATOR. If we set desc_id to be a static variable, checking the return value of rdev_get_id() may return error.
