From f3d4505de539f754b78d5c30e5d2cb41a0ed0117 Mon Sep 17 00:00:00 2001 From: Marek Lindner Date: Wed, 3 Aug 2011 16:35:16 +0200 Subject: [PATCH] ath9k: remove eeprom txgain override for minor version < 19 ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the minor version is not 19 or above with a value of 0. ar9002_hw_init_mode_gain_regs() relies on this information to determine whether this is a high power wifi card or not. The override caused the driver to always use the 'normal' power tables even for high power devices if their minor version was not high enough. Thus leading to reduced power output. This isn't needed for the AR9285; the check originated with the AR9280 setup code which requires the EEPROM version check.
