Subject: drm/mgag200: remove unneeded variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9fe4b9b2ad4f2b801fdff3d634b07c9f9fc4327;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/mgag200: remove unneeded variable

ttm_bo_validate() returns 0 or error. So we can return the value
directly and remove the variable 'ret'.
