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: https://hverkuil.home.xs4all.nl/logs/Friday.log Too many of these appear to be incorrect errors. Can you take a look? Regards, Hans
