[PATCH v5 06/17] media: uapi: HEVC: Change pic_order_cnt definition in v4l2_hevc_dpb_entry

[Benjamin Gaignard <benjamin.gaignard@collabora.com>]

HEVC specifications say that:
"PicOrderCntVal is derived as follows:
PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb
The value of PicOrderCntVal shall be in the range of −231 to 231 − 1, inclusive."

To match with these definitions change __u16 pic_order_cnt[2]
into __s32 pic_order_cnt_val.

Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com>
---
version 5:
- change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val
