Sorry, but I don't accept pull requests. I need patches in email form, as described in the file, Documentation/stable_kernel_rules.txt. Please feel free to send them from your git tree that way. > On Thu, 2012-02-09 at 13:44 +0200, Tomi Valkeinen wrote: > > Hi, > > > > There is a hardware bug on OMAP4, which may cause the HDMI output to > > break irreversibly.
