Subject: V4L/DVB: v4l2_subdev: Move interrupt_service_routine ptr to v4l2_subdev_core_ops Author: Andy Walls <[email protected]> Date: Sun Jul 18 20:54:52 2010 -0300 The CX2584x and related cores are multifunction subdevices with a number of internal blocks that act as interrupt sources. Move the v4L2_subdev interrupt_service_routine callback from v4l_subdev_ir_ops to v4l2_subdev_core_ops, as the video and audio blocks of a CX2584x and related cores can generate interrupts along with the IR block. This change also makes sense for other subdev's that generate interrupts and do not have an IR block.
