+Subject: [PATCH] media: uapi: Add hevc ctrls for WPP decoding
+
+WPP can allow greater parallelism within the decode, but needs
+offset information to be passed in.
+
+Adds num_entry_point_offsets and entry_point_offset_minus1 to
+v4l2_ctrl_hevc_slice_params.
+
+This is based on Jernej Skrabec's patches for cedrus which
+implement the same feature.
