From ea486e681188d64c6a101d8d06414aef0f9f0cd3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 24 Dec 2009 21:40:43 -0800 Subject: Input: serio - do not mark kseriod freezable anymore We used to make kseriod freezable to prevent unnecessary attempts at resuming keyboard and mouse before taking hibernation image when suspend and hibernation were sharing PM operations. Now that they are separated and we don't risk resuming during 'thaw' we don't need to freeze kseriod anymore. This will allow us to start resetting mouse and keyboard a bit earlier, before rest of the userspace comes back up. Acked-by: Rafael J.

However, there is a period when interrupts are kept off, and if key happens to be pressed during that time KBC becomes jammed. To avoid the jam we simply need to poll KBC once during thaw.
