[PATCH] media: uapi: v4l: Change V4L2_TYPE_IS_CAPTURE condition
From: Nas Chung
Date: Fri May 17 2024 - 05:50:04 EST
We expect V4L2_TYPE_IS_CAPTURE() macro allow only CAPTURE type.
But, Inverting OUTPUT type can allow undefined v4l2_buf_type.
Check CAPTURE type directly instead of inverting OUTPUT type.
