From d26769446f5389fa5dd5b8745ddc12d4371fc267 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Thu, 16 Aug 2012 11:14:18 +0100 Subject: [PATCH] staging: comedi: amplc_pc263: add helper functions to check bus type Add inline helper function is_isa_board(board) to check if the driver supports ISA boards and this is an ISA board, and is_pci_board(board) to check if the driver supports PCI boards and this is a PCI board.
