6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov dmitry.torokhov@gmail.com
[ Upstream commit 687fe7dfb736b03ab820d172ea5dbfc1ec447135 ]
Remove option having i2c client contain raw gpio number instead of proper IRQ number. There are no users of this facility in mainline and it will allow cleaning up the driver code with regard to wakeup handling, etc.
