From c5665dfb902f84002e14d30d97b47886fc9fe161 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 4 Apr 2017 11:29:54 +0100 Subject: [PATCH] staging: comedi: amplc_pci230: convert CLK_CONFIG() macro to function Convert the `CLK_CONFIG(chan, src)` macro to a static function `pci230_clk_config(chan, src)`. This is consistent with an earlier change to convert `GAT_CONFIG(chan, src)` to a static function.
