[igt-dev] [PATCH i-g-t 1/3] tests/kms_fbcon_fbt: Check for psr before keeling over

[Daniel Vetter]

Not exactly sure where this broke, or whether it ever worked, but the
psr_disable helper calls igt_skip if psr doesn't work. Which means we
neeed to check for that first.

In general lib/igt_psr.c seems to be a library in dire need of some TLC.
