Subject: drm/udl: unlock before returning in udl_gem_mmap()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ace281e8ab62e026b95c413db5f3c6beed42b829;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/udl: unlock before returning in udl_gem_mmap()

If we hit an error here, then we should unlock and unreference obj
before returning.
