Subject: hotplug-sniffer: Drop "volatile" from g_once_init_enter() sentinels
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~616^2^2~93
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=4dfc53cade812e3b63205620fa13e31955e72763;p=gnome-shell.git

hotplug-sniffer: Drop "volatile" from g_once_init_enter() sentinels

As documented in g_once_init_enter(): "While @location has a volatile qualifier,
this is a historical artifact and the pointer passed to it should not be
volatile.". And effectively this now warns with modern glibc.

Drop this from our logging function.
