From 935477ed7b537cf28b38f0c6b4471915d8c0e12a Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 25 Oct 2014 17:19:26 +0200 Subject: [PATCH] ath9k_hw: make support for PC-OEM cards optional The initvals use up quite a bit of space, and PC-OEM support is typically not needed on embedded systems Signed-off-by: Felix Fietkau Signed-off-by: John W.
