Subject: [PATCH] pinctrl: nuvoton: wpcm450: Convert irqchip to IRQCHIP_IMMUTABLE
Date: Mon, 6 Jun 2022 23:43:00 +0200 [thread overview]
Message-ID: <20220606214301.2061467-1-j.neuschaefer@gmx.net> (raw)
Commit 6c846d026d490 ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning for irqchips that are not marked with
IRQCHIP_IMMUTABLE.
Convert the pinctrl-wpcm450 driver to an immutable irqchip.
