From 487f0e010cf5b6ba504150dfb20c21fd93e3b9e6 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 23 Jul 2010 04:31:56 +0200 Subject: [PATCH] ath9k_hw: simplify noisefloor calibration chainmask calculation The noisefloor array index always corresponds to the rx chain number it belongs to (with an offset of 3 for the extension chain). It's much simpler (and actually more correct) to directly use the chainmask to calculate the bitmask for the noisefloor array, instead of using these weird chip revision checks and hardcoded mask values.
