+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.
