From ebe9f7b02590d870506ef493483fe4abdb08e967 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Fri, 21 Sep 2012 10:36:47 +0530 Subject: [PATCH] video: exynos_mipi_dsi: Remove unnecessary NULL check 'dsim' is allocated and checked for NULL in the probe function. Hence this check is redundant. This cleanup also fixes a potential NULL pointer dereference error when dsim which is NULL references its member in the error print message.
