3ed9a335cf drm/radeon/pm: don't walk the crtc list before it has been initialized (v2) 
Avoids a crash in certain cases when thermal irqs are generated
before the display structures have been initialized.

v2: fix the vblank and vrefresh helpers as well

e14cd2bbcb drm/radeon/dpm: switch on new late_enable callback 
Right now it's called right after enable, but after
reworking the dpm init order, it will get called later
to accomodate loading the smc early, but enabling
thermal interrupts and block powergating later after
the ring tests are complete.

41cd0b3b78 drm/radeon: clean up r600_free_extended_power_table() 
kfree() can accept NULL pointers so I have removed the checks.  Also
I've used a pointer to shorten the lines.

5b7d245009 drm/radeon: gcc fixes for extended dpm tables 
Newer versions of gcc seem to wander off into the
weeds when dealing with variable sizes arrays in
structs.  Rather than indexing the arrays, use
pointer arithmetic.
