Subject: drm/omap: fix memory leak when FB init fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95552191f0a0c3632808d8883fc05d37a5c2fe14;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/omap: fix memory leak when FB init fails

omap_framebuffer_create() fails to unref all the gem objects if creating
the FB fails, leading to a memory leak.

Fix the loop so that it goes through all the reffed gem objects.
