[PATCH 1/2] staging: comedi: addi_apci_1564: remove check for timer subdevice

From: Chase Southwood
Date: Wed May 07 2014 - 03:04:13 EST


The only board served by this driver always has a timer, so we can init
the timer subdevice without checking first.

The boardinfo about the timer can also be removed and the data used
directly.
