Subject[PATCH v1 1/1] gpio: gpio-crystalcove: Skip IRQ CTRL register update for virtual GPIOs
Date
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

Commit 9a752b4c9ab9 ("gpio: crystalcove: Do not write regular gpio
registers for virtual GPIOs") added support to skip GPIO register
update for virtual GPIOs, but it missed to add skip logic in
crystalcove_update_irq_ctrl() function. This patch fixes it.
