From 30bd3a3092c17dbfa18f042ca0815758e8d34e65 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Wed, 19 May 2010 10:31:21 +0900 Subject: [PATCH] ath5k: clarify logic when to enable spur mitigation filter The old code logically did not make sense and seems to have been confused by the fact that we could have newer EEPROMs on older hardware. In any case the spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424. Spur info is available only from EEPROM versions bigger than 5.3 but but the EEPOM routines will use static values for older versions, so that should be o.k.
