Subject: [PATCH v1 4/4] media: camss: vfe: Rework vfe_hw_version_read() function definition
Expose the VFE version by returning the value read from the HW_VERSION
register.
Secondly, change the name of this function to conform with the CSID
equivalent.
Signed-off-by: Robert Foss <robert.foss@...aro.org>
