Subject: drm/omap: do not use BUG_ON(!spin_is_locked(x))
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8519c62ce610e512722d1d8e3991c02cca59010c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/omap: do not use BUG_ON(!spin_is_locked(x))

spin_is_locked(x) returns always 0 on uniprocessor, triggering BUG() in
omapdrm.

Change it to use assert_spin_locked() to fix the issue.
