Subject: [PATCH 4.9 33/42] iio: stk3310: Dont return error code in interrupt handler
Date: Mon, 13 Dec 2021 10:30:15 +0100 [thread overview]
Message-ID: <20211213092927.637859227@linuxfoundation.org> (raw)
In-Reply-To: <20211213092926.578829548@linuxfoundation.org>
From: Lars-Peter Clausen <lars@metafoo.de>
commit 8e1eeca5afa7ba84d885987165dbdc5decf15413 upstream.
Interrupt handlers must return one of the irqreturn_t values. Returning a
error code is not supported.
The stk3310 event interrupt handler returns an error code when reading the
flags register fails.
Fix the implementation to always return an irqreturn_t value.
Fixes: 3dd477acbdd1 ("iio: light: Add threshold interrupt support for STK3310")
