Hi all,

After merging the mmc tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/mmc/host/dw_mmc.c: In function 'dw_mci_wait_hw_unbusy':
drivers/mmc/host/dw_mmc.c:239:16: warning: unused variable 'irqflags' [-Wunused-variable]
  unsigned long irqflags;
                ^~~~~~~~

Introduced by commit

  705a0f288113 ("mmc: dw_mmc: Add hardware unbusy interrupt support")

Yes, the 0-day bot already complained about this.  The short answer is
that Ulf kindly volunteered to manually fix up my patch series where I
had introduced a variable in the wrong patch.  ...but in doing so he
introduced a small bug.

It should be very easy to fix.  Just need to change irqflags from
"unsigned int" to "unsigned long".
