Hi Dan,
With the latest smatch I get a lot of 'uninitialized symbol' errors that
all appear to be related to the use of the min/max/abs macros.
It's clearly seen here:
include/media/v4l2-rect.h:127 v4l2_rect_intersect() error: uninitialized symbol 'bottom'.
include/media/v4l2-rect.h:128 v4l2_rect_intersect() error: uninitialized symbol 'right'.
drivers/media/usb/uvc/uvc_v4l2.c:445 uvc_v4l2_set_streamparm() error: uninitialized symbol 'maxd'.
drivers/media/usb/uvc/uvc_v4l2.c:457 uvc_v4l2_set_streamparm() error: uninitialized symbol 'd'.
The logs of my daily media build from last night are here:

Too many of these appear to be incorrect errors.
Can you take a look?
Regards,
Hans
