[PATCH 5.4 158/203] media: hantro: Set H264 FIELDPIC_FLAG_E flag correctly

From: Greg Kroah-Hartman
Date: Thu Jan 16 2020 - 18:26:32 EST


From: Jonas Karlman <jonas@xxxxxxxxx>

commit a2cbf80a842add9663522bf898cf13cb2ac4e423 upstream.

The FIELDPIC_FLAG_E bit should be set when field_pic_flag exists in stream,
it is currently set based on field_pic_flag of current frame.
The PIC_FIELDMODE_E bit is correctly set based on the field_pic_flag.

Fix this by setting the FIELDPIC_FLAG_E bit when frame_mbs_only is not set.
