From 4237081e573b99a48991aa71364b0682c444651c Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Tue, 20 Feb 2007 01:33:39 +0100 Subject: HID: fix bug in zeroing the last field byte in output reports d4ae650a904612ffb7edd3f28b69b022988d2466 introduced zeroing of the last field byte in output reports in order to make sure the unused bits are set to 0. This is done in a wrong way, resulting in a wrong bits being zeroed out (not properly shifted by the field offset in the report). Fix this.
