Subject: drm/radeon: drop RADEON_FENCE_SIGNALED_SEQ v2
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6d5c5b8364bcc4d52cddc68bcb0a330d2af20f3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/radeon: drop RADEON_FENCE_SIGNALED_SEQ v2

It's causing issues with VMID handling and comparing the
fence value two times actually doesn't make handling faster.

v2: rebased on reset changes
