From 8a8d0875a5ccf14a6772b3bbffa1717e668a0d8a Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 13 Nov 2015 11:11:05 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: remove 'has_counter' boardinfo All the boards supported by this driver have a 8254 counter. Channels 1 and 2 are used to create the cascaded 32-bit analog input pacer. Counter 0 is available for the user on all the boards except the PCI-1713. Remove the 'has_counter' boardinfo and use the 'is_pci1713' boardinfo to determine if the user counter subdevice needs to be allocated and initialized.
