Subject: [PATCH v2] media: camss: vfe: Don't call hw_version() before its dependencies are met
Date: Thu, 12 Aug 2021 11:21:52 +0200 [thread overview]
Message-ID: <20210812092152.726874-1-robert.foss@linaro.org> (raw)
vfe->ops->hw_version(vfe) is being called before vfe->base has been
assigned, and before the hardware has been powered up.
Fixes: b10b5334528a9 ("media: camss: vfe: Don't read hardware version needlessly")
Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>
Reported-by: Marek Szyprowski <m.szyprowski@samsung.com>
