MSDK plugin fails to build with libva 2.4.0

Just tried to build the plugin today with latest libva 2.4.0 (api 1.4.0) and it failed with the following.

msdk_libva.c:52:25: error: ‘VA_FOURCC_A2R10G10B10’ undeclared here (not in a function)

It seems it might be missing some libva guard because VA_FOURCC_A2R10G10B10 is introduced in api 1.5.0 so far I understand.
