[alsa-devel] [PATCH] ASoC: twl6040: No need to read the INTID register

[Peter Ujfalusi]

Since our irq handler has been called, it is granted, that
the reason was either PLUGINT, or UNPLUGINT.
The INTID register has been checked in the MFD part of
twl6040 driver (twl6040-irq.c).
We have no reason to read from chip again here.
