Subject: [bug report] ath9k: Fix issue with MCS15
Date: Thu, 17 May 2018 17:21:00 +0300 [thread overview]
Message-ID: <20180517142100.GA22656@mwanda> (raw)
Hello Sujith Manoharan,
The patch 6fcbe538be43: "ath9k: Fix issue with MCS15" from Nov 14,
2013, leads to the following static checker warning:
drivers/net/wireless/ath/ath9k/ar9003_phy.c:836 ar9003_doubler_fix()
warn: 'ah->hw_version.macVersion == 448' 'false' implies 'ah->hw_version.macVersion == 448' is 'false'
drivers/net/wireless/ath/ath9k/ar9003_phy.c
834 static void ar9003_doubler_fix(struct ath_hw *ah)
835 {
836 if (AR_SREV_9300(ah) || AR_SREV_9580(ah) || AR_SREV_9550(ah)) {
The problem is that both AR_SREV_VERSION_9300 and AR_SREV_VERSION_9580
are 0x1c0 so the test for AR_SREV_9580() is duplicative.
837 REG_RMW(ah, AR_PHY_65NM_CH0_RXTX2,
838 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHON_MASK_S |
839 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHOVR_MASK_S, 0);
840 REG_RMW(ah, AR_PHY_65NM_CH1_RXTX2,
841 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHON_MASK_S |
842 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHOVR_MASK_S, 0);
843 REG_RMW(ah, AR_PHY_65NM_CH2_RXTX2,
844 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHON_MASK_S |
845 1 << AR_PHY_65NM_CH0_RXTX2_SYNTHOVR_MASK_S, 0);
846
847 udelay(200);
