After applying this patch and enabling the driver I get a kernel panic
on every boot up on my DM355 EVM from Spectrum Digital. With some
experimentation I found that the panic only happens when I enable
CONFIG_VIDEO_DM355_CCDC. I have applied all but #6 in this series to the
davinci-linux git tree as well as v3 of the
TVP514x-Migration-to-sub-device-framework patch (which I believe is the
one mentioned in the second note. Does anything obvious that I might be
missing jump out at anyone? I've attached the log of the kernel panic.
Thanks in advance,
