Subject: v4l2-ctl: report max_num_buffers
Author:  Hans Verkuil 
Date:Tue Jan 16 11:34:34 2024 +0100

stream_buf_caps() didn't report the max_num_buffers value, just the
corresponding capability flag. Add this.

[git:v4l-utils/master] meson.build: dep_systemd was not set in one case

Subject: meson.build: dep_systemd was not set in one case
Author:  Hans Verkuil 
Date:Tue Jan 16 14:26:41 2024 +0100

If the systemdsystemunitdir option was set, then dep_systemd
was never set, causing meson to fail. Just always set this.
