X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c64bd26f7e9bd589ebe0d1ebec69ef2f784c12d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/radeon: tweak ACCEL_WORKING2 query for hawaii

Return 2 so we can be sure the kernel has the necessary
changes for acceleration to work.

Note: This patch depends on these two commits:
 - drm/radeon: fix cut and paste issue for hawaii.
 - drm/radeon: use packet2 for nop on hawaii with old firmware
