Subject: [PATCH 2/3] wifi: brcm80211: Remove more unused functions
From: "Dr. David Alan Gilbert" <linux@...blig.org>
This is a subset of unused functions in bcrmsmac phy_cmn.c,
They're unused since the original 2010
commit a9533e7ea3c4 ("Staging: Add initial release of brcm80211 - Broadcom
802.11n wireless LAN driver.")
Remove them.
Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
