I have now verified the code on a DM6446 and DM355, with
the ./fbdev_loopback test. I had to first do a #./i2cset -y 0 0x50 0x00
0x0000 w to kill the bus and then run the ./fbdev_loopback test to
recreate the issue. Recovery seems to happen with the new patch. Could
you try this out at your end, with the new patch?

Thanks and regards,
Philby
