Subject: drm/radeon: only warn once in radeon_ttm_bo_destroy if va list not empty
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=634b6a8a064576797120b74facf95ba79283b5d5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/radeon: only warn once in radeon_ttm_bo_destroy if va list not empty

Encountered a dozen of exact same backtraces when mesa's
pb_cache_release_all_buffers is called after that a gpu reset failed.

v2: Remove superfluous error message added in v1.
