From 0b5ead91cda63e0db964dadc77601233434f60cb Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Tue, 7 Dec 2010 16:31:38 +0530 Subject: [PATCH] ath9k_htc: Cleanup device identification ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc. Adding driver specific data to the shared structure would impact all the drivers. Handling USB device recognition for devices specific to ath9k_htc can be handled within the driver itself. Also, AR7010 refers to the processor used in both AR9280/AR9287 based devices. Rename the device enumerations accordingly. While at it, check properly for the bus type when choosing the EEPROM base address for UB95. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
