commit 1c9c02bb22684f6949d2e7ddc0a3ff364fd5a6fc upstream.
Update logic for broken test. Use a more common logging style.
It appears the logic in this function is broken for the consecutive tests of
if (prog_status & 0x3) ... else if (prog_status & 0x2) ... else (prog_status & 0x1) ...
Likely the first test should be
if ((prog_status & 0x3) == 0x3)
Found by inspection of include files using printk.
