gpio: gpio-wcove: fix irq pending status bit width
Whiskey cove PMIC has three GPIO banks with total number of 13 GPIO pins. But when checking for the pending status, for_each_set_bit() uses bit width of 7 and hence it only checks the status for first 7 GPIO pins missing to check/clear the status of rest of the GPIO pins. This patch fixes this issue. Signed-off-by: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
