Subject: [media] coda: Unregister v4l2 upon alloc_workqueue() error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=74d08d55ed978bd60d4774083f700e6630fe42a5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] coda: Unregister v4l2 upon alloc_workqueue() error

If alloc_workqueue() fails, we should go to the 'err_v4l2_register' label, which
will unregister the v4l2 device.
