From 760d969f9e91a734161a5979a3b3818062e80b7e Mon Sep 17 00:00:00 2001 From: Teemu Paasikivi Date: Mon, 22 Feb 2010 08:38:25 +0200 Subject: [PATCH] wl1271: Removed wl1271_spi.h and made some functions static Removed wl1271_spi.h header as there's no more need to access functions declared there outside of wl1271_spi.c. Also made those SPI access functions static. Signed-off-by: Teemu Paasikivi Reviewed-by: Juuso Oikarinen Signed-off-by: Juuso Oikarinen Signed-off-by: John W.
