Subject: RE: [PATCH resend] scsi: smartpqi: add missed free_irq in suspend

-----Original Message-----

The driver calls request_irq in resume but does not call free_irq in suspend.
Add the missed call to fix it.

Signed-off-by: Chuhong Yuan <hslester96@...il.com>

NAK: free_irq is called in pqi_resume after checking for correct power state change. (in pqi_free_interrupts())

Thanks for your review,
Don
