From db36c9d6a6be232bdee245407fc8ccde53ea69c6 Mon Sep 17 00:00:00 2001 From: Gabor Juhos <juhosg@openwrt.org> Date: Mon, 4 Feb 2013 11:58:49 +0100 Subject: [PATCH] MIPS: ath79: remove unused ar7{1x,24}x_pcibios_init functions commit 6e783865b4e60f2ecf7708f8ea24db5c5ea07ced upstream. The functions are unused now, so remove them.
