Subject: drm/prime: clarify logic a bit in drm_gem_prime_fd_to_handle
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84341c280acb8217a301344082c7ad8b9af870a6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/prime: clarify logic a bit in drm_gem_prime_fd_to_handle

if (!ret) implies that ret == 0, so no need to clear it again. And
explicitly check for ret == 0 to indicate that we're checking an errno
integer.
