From 325089ab5847f5c1e43f42bb90d32f981867c4c1 Mon Sep 17 00:00:00 2001 From: Nick Kossifidis Date: Tue, 23 Nov 2010 21:02:20 +0200 Subject: [PATCH] ath5k: Small cleanup on tweak_initvals * Now that we properly set rx/tx latencies for AR5311 remove that old buggy part of code left inside ath5k_hw_tweak_initval_settings that was never executed (you can't have an RF5112 radio on a mac older than AR5212). Also use a magic value for 5311 PHY_SCAL value. Signed-off-by: Nick Kossifidis Signed-off-by: John W.
