Subject: Re: [PATCH] drm/bridge: dw-mipi-dsi.c: Add VPG runtime config
through debugfs
Hi Angelo,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linus/master]
[also build test ERROR on v5.6 next-20200404]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
