Subject: [PATCH AUTOSEL 6.1 02/29] HID: cp2112: Fix driver not registering GPIO IRQ chip as threaded
Date: Sun, 19 Mar 2023 20:53:44 -0400 [thread overview]
Message-ID: <20230320005413.1428452-2-sashal@kernel.org> (raw)
In-Reply-To: <20230320005413.1428452-1-sashal@kernel.org>
From: Danny Kaehn <kaehndan@gmail.com>
[ Upstream commit 37f5b858a66543b2b67c0288280af623985abc29 ]
The CP2112 generates interrupts from a polling routine on a thread,
and can only support threaded interrupts. This patch configures the
gpiochip irq chip with this flag, disallowing consumers to request
a hard IRQ from this driver, which resulted in a segfault previously.
