[PATCH] gpio: crystalcove: Fix implicit declaration of function 'seq_printf' error

[Lee Jones <lee.jones@xxxxxxxxxx>]

drivers/gpio/gpio-crystalcove.c: In function 'crystalcove_gpio_dbg_show':
drivers/gpio/gpio-crystalcove.c:286:3: error: implicit declaration of function 'seq_printf'
   seq_printf(s, " gpio-%-2d %s %s %s %s ctlo=%2x,%s %s %s\n",

I'm looking for a quick Ack on this patch.  It's a fix to an immutable
branch that I'm carrying which is shared between GPIO and MFD.  Stephen
reported it when the MFD tree was sucked into -next.

Alexandre,
  I believe Linus is out on vacation this week, so if you could take a
quick look at this, I'd be much obliged.

Linus,
  Once I've acquired the aforementioned Ack I'll fix this patch up into
our immutable branch and send another pull-request.
