The one byte missing in stack based buffer buf can cause stack corruption possibly leading to kernel oops, as discovered originally with af9015 driver (af9015: fix stack corruption bug).

The xc3028 never recovers after setting the powerdown register, which is probably because the xc3028 reset GPIO is not properly configured. Since I do not have access to the hardware and thus cannot determine the correct GPIO configuration, just disable xc3028 power management on this board, which fixes the regression. Thanks to user "ritec" for reporting the issue and testing the fix.
