From 2a8281d72da5dd8da025e6822dadd23a35383895 Mon Sep 17 00:00:00 2001 From: Daniel Ritz Date: Mon, 10 Sep 2007 01:31:40 -0400 Subject: [PATCH] Input: usbtouchscreen - support DMC devices with empty EEPROM A reply of 0x0600 means all OK, 0x1501 means OK, but EEPROM empty. The behavior with an empty EEPROM is the same as without one at all so do not fail loading the driver.
