+Subject: media: videobuf2-v4l2: drop WARN_ON in vb2_warn_zero_bytesused()
+
+From: Hans Verkuil <hverkuil-cisco@xs4all.nl>
+
+commit 5e99456c20f712dcc13d9f6ca4278937d5367355 upstream.
+
+Userspace shouldn't set bytesused to 0 for output buffers.
+vb2_warn_zero_bytesused() warns about this (only once!), but it also
+calls WARN_ON(1), which is confusing since it is not immediately clear
+that it warns about a 0 value for bytesused.
+
+Just drop the WARN_ON as it serves no purpose.
