Colin Ian King 3b82a051c1 drivers/block/zram/zram_drv.c: fix error return codes not being returned in writeback_store ... Currently when an error code -EIO or -ENOSPC in the for-loop of writeback_store the error code is being overwritten by a ret = len assignment at the end of the function and the error codes are being lost. Fix this by assigning ret = len at the start of the function and remove the assignment from the end, hence allowing ret to be preserved when error codes are assigned to it.
