+Subject: Fix linux up_backend_supports_sleep_state() return code.
+
+Under Linux, regardless of the exit code of /usr/bin/pm-is-supported, it will
+always set CanSuspend and CanHibernate to true due to a logic error in
+up_backend_supports_sleep_state in src/linux/up-backend.c: The 'ret' variable
+is re-used for the return code without being re-initialized to false after the
+call to g_spawn_command_line_sync.
