Subject: drm/i915/fbdev: Call intel_unpin_fb_obj() on release
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb4b8ce139c36fe93cf006bd68f0aa0340dd59e8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/fbdev: Call intel_unpin_fb_obj() on release

When releasing the intel_fbdev, we should unpin the framebuffer that we
pinned during construction.
