[PATCH 05/11] rcar-vin: Rename array storing subdevice information

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

 



The VIN group have always been connected to CSI-2 receivers and this
have spilled over to the naming of the array storing the subdevice
information. In preparation for connecting other types of subdevices
rename the array to remotes.
