From 7d9852a88cb76b102b60b31949d5777e645f1421 Mon Sep 17 00:00:00 2001 From: Thomas Pugliese Date: Thu, 6 Jun 2013 10:40:49 -0500 Subject: [PATCH] wusbcore: reduce keepalive threshold from timeout/2 to timeout/3 This patch reduces the keepalive threshold of WUSB host controllers from timeout/2 to timeout/3. The keepalive timer fires every timeout/2 ms, but due to rounding errors and jitter, the host may decide not to send a keepalive at timeout/2. By the time the next timer fires, a full timeout period may have expired causing the device to be disconnected without ever having been sent a keepalive. Changing the keepalive threshold to timeout/3 ensures that at least one keepalive will be sent before a device is disconnected. The patch also updates the code to use msecs_to_jiffies consistently.
