-Subject: [PATCH] spi: qup: Ensure done detection
-
-This patch fixes an issue where a SPI transaction has completed, but the done
-condition is missed.  This occurs because at the time of interrupt the
-MAX_INPUT_DONE_FLAG is not asserted.  However, in the process of reading blocks
-of data from the FIFO, the last portion of data comes in.
-
-The opflags read at the beginning of the irq handler no longer matches the
-current opflag state.  To get around this condition, the block read function
-should update the opflags so that done detection is correct after the return.
