you do it wrong, please *immedately* stop sending this kind of patches
and revoke all the ones which you have sent so far, one revoke message
for each sent patch is expected.

1) there must be no error level message printed out, if the returned
   by platform_get_irq() value is -EPROBE_DEFER, this notice makes
   all your patches *invalid*,

2) if you wish it, add the error message directly into platform_get_irq(),
   then *remove* any similar error messages from the individual drivers.
