Subject: [PATCH v3 2/7] mfd: tqmx86: clear GPIO IRQ resource when no IRQ is set
Date: Fri, 16 Jul 2021 12:00:48 +0200 [thread overview]
Message-ID: <65f9787ebd6725e90fad9ea7f936ee0d5712da94.1626429286.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 driver was registering IRQ 0 when no IRQ was set. This leads to
warnings with newer kernels.
Clear the resource flags, so no resource is registered at all in this
case.
Fixes: 2f17dd34ffed ("mfd: tqmx86: IO controller with I2C, Wachdog and GPIO")
