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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
