Subject: [PATCH v3 1/7] gpio: tqmx86: really make IRQ optional
Date: Fri, 16 Jul 2021 12:00:47 +0200 [thread overview]
Message-ID: <34be64092b7b4d0c75085a8c729f5f6fcfb56b61.1626429286.git.matthias.schiffer@ew.tq-group.com> (raw)
In-Reply-To: <cover.1626429286.git.matthias.schiffer@ew.tq-group.com>
In-Reply-To: <cover.1626429286.git.matthias.schiffer@ew.tq-group.com>
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")
