[PATCH] firmware_class: fix typo in error path
From: Johannes Berg
Date: Wed Aug 18 2010 - 11:15:28 EST
From: Johannes Berg <johannes.berg@xxxxxxxxx>
In the error path, _request_firmware sets
firmware_p to NULL rather than *firmware_p,
which leads to passing a freed firmware
struct to drivers when the firmware file
cannot be found. Fix this.
Broken by commit f8a4bd3456b988fc73b2c.
