Subject: [PATCH] radeon/pm: Guard access to rdev->pm.power_state array
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8

commit 370169516e736edad3b3c5aa49858058f8b55195 upstream.

It's never allocated on systems without an ATOMBIOS or COMBIOS ROM.

Should fix an oops I encountered while resetting the GPU after a lockup
on my PowerBook with an RV350.
