Subject: [media] v4l2-ioctl: add blocks check for VIDIOC_SUBDEV_G/S_EDID
X-Git-Tag: v3.7-rc1~38^2^2~5

[media] v4l2-ioctl: add blocks check for VIDIOC_SUBDEV_G/S_EDID

The maximum size of an EDID is 32768 bytes, which is 32768 / 128 = 256 blocks.
Return -EINVAL if blocks > 256 to ensure that the memory allocation is sane.
