scsi: ufs: make sure all interrupts are processed
[ Upstream commit 7f6ba4f12e6cbfdefbb95cfd8fc67ece6c15d799 ]
As multiple requests are submitted to the ufs host controller in
parallel there could be instances where the command completion interrupt
arrives later for a request that is already processed earlier as the
corresponding doorbell was cleared when handling the previous
interrupt. Read the interrupt status in a loop after processing the
received interrupt to catch such interrupts and handle it.
