From 37869fa2da1a952ed736858f8b9e45c0b9131ae9 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 20 May 2009 14:30:06 +0000 Subject: sh: ap325 camera without i2c driver fix This patch fixes the ap325rxa ncm03j camera code to handle the case where no i2c driver is present. Without this fix i2c_transfer() may be passed NULL as adapter which results in a crash. Triggered when i2c-sh_mobile.c failed to probe() due to missing MSTP clocks.
