X-Git-Tag: v5.15-rc1~148^2~23^2~56
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9aa0267476eda3c77890dd939fb2579bffceb3ae;p=thirdparty%2Fkernel%2Flinux.git

drm/vram-helper: Unexport drm_vram_helper_{alloc,release}_mm()

All GEM-VRAM-based drivers use auto-cleanup via drmm_vram_helper_init().
Unexport the manual APIs and make them internal implementation.
