Subject: [RFC PATCH V0 2/4] media: subdev: support which in v4l2_subdev_frame_interval
Date:   Wed, 5 May 2021 16:06:24 +0800

This patch is to support try or set of VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL
through which parameter.
This behavior is already supported in some similar V4L2 IOCTLs such as
VIDIOC_SUBDEV_ENUM_FRAME_SIZE for the same reason.
