The patch titled pm: serio: speed up resume has been removed from the -mm tree. Its filename was pm-serio-speed-up-resume.patch This patch was dropped because conflicting code has been merged into linux-next The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: pm: serio: speed up resume From: Shaohua Li <shaohua.li@xxxxxxxxx> Subject: serio: Speed-up resume serio_resume will call into psmouse_extensions(). In my test, the routine is very slow, it blocks resume about 1 sec. Below patch (move resume to kseriod, just like boot time probe) cures the issue in my test, and seems no side effect. I'm no familiar with serio driver, so please check. Signed-off-by: Shaohua Li <shaohua.li@xxxxxxxxx> Acked-by: Len Brown <lenb@xxxxxxxxxx> Signed-off-by: Rafael J.
