Subject: drm/omap: clear omap_obj->paddr in omap_gem_put_paddr()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f4d17c4eca9769d56218a38dbfc482794fbde2f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/omap: clear omap_obj->paddr in omap_gem_put_paddr()

Clear omap_obj's paddr when unmapping the memory, so that it's easier to
catch bad use of the paddr.
