drm/amdgpu: Use gmc->noretry instead of amdgpu_noretry directly2026-06-03T17:50:10+00:00Timur Kristóftimur.kristof@gmail.com2026-05-25T11:45:01+00:00urn:sha1:003851b532f33a024f26feefb7e133ec413b7a6f
Whether retry faults are actually enabled, is determined by
the amdgpu_gmc_noretry_set() function. The rest of the code
base should use gmc->noretry instead of the module parameter.
