6.12-stable review patch. If anyone has any objections, please let me know.

From: Laurentiu Palcu <laurentiu.palcu@xxxxxxxxxxx>
[ Upstream commit 7b12ab055edef2f51733d155617a401a05237bcc ]
Running the v4l2-compliance (1.27.0-5208, SHA: af114250d48d) on the m2m
device fails on the MMAP streaming tests, with the following messages:
fail: v4l2-test-buffers.cpp(240): g_field() == V4L2_FIELD_ANY
fail: v4l2-test-buffers.cpp(1508): buf.qbuf(node)
Apparently, the driver does not properly set the field member of
vb2_v4l2_buffer struct, returning the default V4L2_FIELD_ANY value which
is against the guidelines.
