From 623f41eb923d7f34888cbd9e4f50a7b1a79d0ae5 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 21 Apr 2005 22:06:13 -0700 Subject: [PATCH] [SPARC64]: In sunsu driver, make sure to fully init chip for kbd/ms We were forgetting to call sunsu_change_speed(). The reason that replugging in the mouse cable "fixes things" is that causes a BREAK interrupt which in turn caused a call to sunsu_change_speed() which would get the chip setup properly.
