[PATCH v1 3/3] staging: media: imx: imx7-mipi-csis: Make subdev name unique

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When multiple CSIS instances are present in a single graph, they are
currently all named "imx7-mipi-csis.0", which breaks the entity name
uniqueness requirement. Fix it by using the device name to create the
subdev name.
