Subject: [PATCH AUTOSEL 6.1 06/15] iio: adc: palmas_gpadc: fix NULL dereference on rmmod
Date: Thu, 20 Apr 2023 07:02:20 -0400	[thread overview]
Message-ID: <20230420110231.505992-6-sashal@kernel.org> (raw)
In-Reply-To: <20230420110231.505992-1-sashal@kernel.org>

From: Patrik Dahlström <risca@dalakolonin.se>

[ Upstream commit 49f76c499d38bf67803438eee88c8300d0f6ce09 ]

Calling dev_to_iio_dev() on a platform device pointer is undefined and
will make adc NULL.
