Subject: [igt-dev] [PATCH i-g-t] lib/igt_psr: Added ENOENT error check to psr_set for older kernels
Date: Fri, 28 Sep 2018 17:01:31 -0700 [thread overview]
Message-ID: <20180929000131.142820-1-casey.g.bowman@intel.com> (raw)
Only EINVAL was being used to account for older kernels,
but on legacy kernels that don't use i915_edp_psr_debug,
the ENOENT error will be thrown. This changes the logic
to also account for ENOENT errors.
