drm/vkms: Drop unnecessary call to drm_crtc_cleanup()

[PATCH] drm/vkms: Drop unnecessary call to drm_crtc_cleanup()

Posted by José Expósito 3 weeks, 3 days ago

CRTC creation uses drmm_crtc_init_with_planes(), which automatically
handles cleanup. However, an unnecessary call to drm_crtc_cleanup() is
still present in the vkms_output_init() error path.

Thanks!

I discussed about this with Maíra on Monday, I agree with this patch!

I will test your patch next week (checkpatch, sparse, CI) before adding
my Acked-by. One less cleanup line in configFS work, thanks!

Thanks,
Louis Chauvet
