From dbdb6248229d1a9f2532cd86dcb8db270ea79034 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 13 Nov 2015 11:11:11 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: remove 'has_large_fifo' and 'has_diff_ai' boardinfo The pci1711/31 boards are the only ones that have a smaller FIFO (1K vs 4K) and single-ended analog inputs (no differential). Replace the 'has_large_fifo' and 'has_diff_ai' members of the boardinfo with 'is_pci1711' and use that to determine how to initialize the analog input subdev_flags as well as the private data 'max_samples'.
