X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dea2e29b9fad48c759aa406b5ea426bff4339af;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/kms/radeon/agp: Move the check of the aper_size after drm_acp_acquire and drm_agp_info First call drm_agp_acquire to check if agp has been acquired. Second call drm_agp_info to fill in the info data struct, including aper_size. Finally do the check to see if the aper_size makes sense.
