[PATCH] mmc: s3cmci: include linux/interrupt.h for tasklet_struct

[PATCH] mmc: s3cmci: include linux/interrupt.h for tasklet_struct

[Arnd Bergmann]

I got this new build error on today's linux-next

drivers/mmc/host/s3cmci.h:69:24: error: field 'pio_tasklet' has incomplete type
  struct tasklet_struct pio_tasklet;
drivers/mmc/host/s3cmci.c: In function 's3cmci_enable_irq':
drivers/mmc/host/s3cmci.c:390:4: error: implicit declaration of function 'enable_irq';did you mean 'enable_imask'? [-Werror=implicit-function-declaration]

While I haven't found out why this happened now and not earlier, the
solution is obvious, we should include the header that defines
the structure.

Yes, it's a bit weird. Actually non of the automated build system have
reported this.

I have my own homebrewed makefiles, as to run a quick sanity test for
mmc host drivers. However, my quick test didn't cover s3cmci, next
time it will.

Thanks for helping out! Applied for next and folded it in properly in
my queue to avoid bisect issues!

Kind regards
