From 5578b1ffdc3091dd0ae164b056fd1224fb00f1e9 Mon Sep 17 00:00:00 2001 From: Prameela Rani Garnepudi Date: Tue, 16 May 2017 15:31:17 +0530 Subject: [PATCH] rsi: Remove old firmware loading method The older firmware loading method is not usable by any Redpine chipset. Hence removing that part of the code. Older firmware image with rsi_91x.fw name is deprecated Signed-off-by: Prameela Rani Garnepudi Signed-off-by: Amitkumar Karwar Signed-off-by: Kalle Valo --- drivers/net/wireless/rsi/rsi_91x_sdio_ops.c | 187 -------------------- drivers/net/wireless/rsi/rsi_91x_usb.c | 6 +- drivers/net/wireless/rsi/rsi_91x_usb_ops.c | 126 ------------- drivers/net/wireless/rsi/rsi_common.h | 3 +- drivers/net/wireless/rsi/rsi_sdio.h | 1 - drivers/net/wireless/rsi/rsi_usb.h | 3 - 6 files changed, 3 insertions(+), 323 deletions(-) diff --git a/drivers/net/wireless/rsi/rsi_91x_sdio_ops.c b/drivers/net/wireless/rsi/rsi_91x_sdio_ops.c index 225042f675ca..df2a63b1f15c 100644 --- a/drivers/net/wireless/rsi/rsi_91x_sdio_ops.c +++ b/drivers/net/wireless/rsi/rsi_91x_sdio_ops.c @@ -59,171 +59,6 @@ int rsi_sdio_master_access_msword(struct rsi_hw *adapter, u16 ms_word) return status;
