Subject: ibmpc_usb: Fix Code Set 2 for Z-150 SysRq
X-Git-Url: https://git.friedersdorff.com/?a=commitdiff_plain;h=2a98bf516a26c6446728f1f3d3bd5ebabf7d1e98;p=max%2Ftmk_keyboard.git

ibmpc_usb: Fix Code Set 2 for Z-150 SysRq

Zenith Z-150 AT sends scan code 0x7F for SysRq.
Accoding to i8042 translation table it maps both 0x7F and
0x84 into 0x54(Print Screen).
