Subject: drm: omapdrm: fb: Simplify objects lookup when creating framebuffer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a39c94e8138f4708b92245a7021ad4d40376360f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: omapdrm: fb: Simplify objects lookup when creating framebuffer

Merge the single-user objects_lookup inline function into its caller,
allowing reuse of the error code path.
