From 26c22324cca2db37fa294156fd875100d95438f4 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 9 Dec 2012 15:19:01 +0100 Subject: [PATCH 3/4] ath9k: use 'struct ath_hw *' as the first argument for 'ath9k_hw_nvram_read' The 'ath9k_hw_nvram_read' function takes a 'struct ath_common *' as its first argument. Almost each of its caller has a 'struct ath_hw *' parameter in their argument list, and that is dereferenced in order to get the 'struct ath_common' pointer. Change the first argument of 'ath9k_hw_nvram_read' to be a 'struct ath_hw *', and remove the dereference calls from the callers. Also change the type of the first argument of the ar9300_eeprom_read_{byte,word} functions.
