From 74673db99ca3c09d34ea479f684522ceedb65eb9 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 8 Sep 2012 15:24:17 +0200 Subject: ath9k: make PA linearization optional, disabled by default and fix checks Some checks for PA linearization support checked ATH9K_HW_CAP_PAPRD and some used the EEPROM ops, leading to issues in tx power handling, since those two can be out of sync. Disable the feature by default, since it has been reported that it can cause damage to the rx path under some circumstances. It can now be enabled for testing via debugfs.
