SubjectRe: [PATCHv2] drm: fb_helper: prefer to use mode, which is not DRM_MODE_TYPE_USERDEF
Hi Chris,

On 04/20/2015 01:00 PM, Chris Wilson wrote:
> Can you do a WARN_ON(list_empty(&connector->modes)) here to see at what

sure please see attached patch adding WARN_ON and corresponding output
of dmesg. As mentioned in the original commit, the mode is indeed added
in drm_helper_probe_add_cmdline_mode.

Thanks,
Radek
