From: Anssi Hannula Date: Sat, 22 Mar 2008 22:50:13 +0000 (+0100) Subject: HID: only dump report traffic with debug level 2 X-Git-Tag: v2.6.26-rc1~1107^2~14 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=377e10fbb4ef219f540d06796e9fb0d3ec35a58f;p=linux-2.6 HID: only dump report traffic with debug level 2 Currently using debug=1 with hid module prints out all sent and received reports to the kernel log, while in many cases we only want to see the report descriptors and hid-input mappings that are printed when a device is probed. Add new level debug=2, and only dump the report traffic with that level.
