[PATCH] gpiolib: Fix missing array end sentinel in quirks array

From: Nicolas Frattaroli
Date: Tue Sep 20 2022 - 10:27:51 EST


Without the sentinel, the loop never actually terminates if there
are no quirks, and wreaks havoc across the kernel resulting in a
juicy panic.

Fix this by adding a NULL at the end.
