The V4L2 devices and subdevices share a few common operations,like opening and closing a device node, and perform IOCTLs on the device. With the forthcoming introduction of support for V4L2 controls, the quantity of shared code will increase, as the control support implementation is identical for the two derived classes. To maximize code re-use and avoid duplications, provide a V4L2Device base class which groups the common operations and members. The newly introduced base class provides methods to open/close a device node, access the file descriptor, and perform IOCTLs on the device.
