Subject: [PATCH] kdrive: fix up NewInputDeviceRequest() implementation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch simplifies NewInputDeviceRequest() implementation in
kinput.c, making use of improved KdParseKbdOptions() /
KdParsePointerOptions() and merging several "if (ki)"/"if (pi)" clauses.
