From 94723bfa7bf1b647fe49c9717ee02e99d7a59957 Mon Sep 17 00:00:00 2001 From: Jamie Lentin Date: Wed, 23 Jul 2014 23:30:45 +0100 Subject: HID: lenovo: Rename hid-lenovo-tpkbd to hid-lenovo Rename module and all functions within so we can add support for other keyboards in the same file. Rename the _tp postfix to _tpkbd, to signify functions relevant to the TP USB keyboard.
