From 89b6e35c2032d74f51333fbf3635d980b3311c68 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Sun, 16 Nov 2014 06:11:05 +0530 Subject: [PATCH] ath9k: Fix thermometer programming The registers that control the on-chip thermometer need to be programmed based on the chainmask that the solution supports, not the chainmask that is present in the eeprom.
