V4L/DVB (11260): v4l2-ioctl: Check format for S_PARM and G_PARM Return EINVAL if VIDIOC_S/G_PARM is called for a buffer type that the driver doesn't define a ->vidioc_try_fmt_XXX() method for. Several other ioctls, like QUERYBUF, QBUF, and DQBUF, etc. do this too. It saves each driver from having to check if the buffer type is one that it supports.
