Subject: [PATCH] gpio: tqmx86: really make IRQ optional
Git-commit: 9b87f43537acfa24b95c236beba0f45901356eb2
Patch-mainline: v5.14-rc5
References: git-fixes
The tqmx86 MFD driver was passing IRQ 0 for "no IRQ" in the past. This
causes warnings with newer kernels.
Prepare the gpio-tqmx86 driver for the fixed MFD driver by handling a
missing IRQ properly.
Fixes: b868db94a6a7 ("gpio: tqmx86: Add GPIO from for this IO controller")
