From 76ed94be65c8bd80b565865c186dd9f24bb2f23b Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Fri, 30 Sep 2011 11:31:28 +0530 Subject: ath9k_hw: set pci_express capability true for AR9480 the AR_SREV register does not seems to indicate whether AR9480 is pci_express capable or not though the other information like macVersion etc can be obtained properly. this fix is essential as ASPM won't be intialized and its related driver functionality ath9k_hw_configpcipowersave won't be called Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: John W.
