Actually I did run checkpatch.pl and found that almost all errors and
warnings are from ehci core (ehci-hcd.c, ehci-hub.c and so on) where
my driver borrowed most of code.

$ ./scripts/checkpatch.pl --terse -f drivers/usb/host/ehci-hub.c | tail -n 1
total: 18 errors, 69 warnings, 1138 lines checked

$ ./scripts/checkpatch.pl --terse -f drivers/usb/host/ehci-hcd.c | tail -n 1
total: 17 errors, 78 warnings, 1403 lines checked

So you're saying that I should fix them, is that right?

thanks,
