- The pinnacle handler & remote are common to saa7134 PCI boards and em28xx
USB boards, so the keymap was moved to ir-common and the keyhandler is back
to ir-kbd-i2c
- request_module("ir-kbd-i2c") is no longer necessary at saa7134-core since
saa7134.ko now depends on ir-kbd-i2c.ko to get the keyhandler
