Irq pointer is first freed and then used in
irq_set_trigger_type and set wakeup capable.
This may lead to Null pointer dereference if
irq is NULL. Free irq after using it.

Headset insertion/removal is not detected sometime due to
fifo read failure due to swr underflow. This is because if
headset sva is enabled, during clk switch swr force stop
happens and if mbhc has already taken pm vote for 3sec
further mbhc reads/writes will fail. If swr is in clk switch
mode then call swrm runtime_resume during reads/writes
to resolve issue.

Headset is not detected if devnum 0 gets detached at bootup.
This is because on detach being called hw will mask interrupt
at slave side but will not unmask it afterwards.
Also device 0 is used only for discovery purpose and
interrupt shouldnt be masked if it detaches.
