From 93110f698fe92fc4dfd86c78783aedf522c69eb9 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Mon, 28 Jul 2008 16:53:05 +0200 Subject: [PATCH] ipwireless: Do not return value from sending funcs ipwireless: Do not return value from sending funcs Do not return value from do_send_fragment and do_send_packet, it's not used. The packet size checks are not useful too: * zero length packet will never be sent, caller always passes packet_header size which is either 1 or 3 * MTU check is done in caller, no need to repeat Signed-off-by: David Sterba Signed-off-by: Jiri Kosina Signed-off-by: Linus Torvalds --- drivers/char/pcmcia/ipwireless/hardware.c | 15 +++------------ 1 file changed, 3 insertions(+), 12 deletions(-) diff --git a/drivers/char/pcmcia/ipwireless/hardware.c b/drivers/char/pcmcia/ipwireless/hardware.c index 08423ba5b9..ff2093d221 100644 --- a/drivers/char/pcmcia/ipwireless/hardware.c +++ b/drivers/char/pcmcia/ipwireless/hardware.c @@ -400,19 +400,14 @@ static void swap_packet_bitfield_from_le(unsigned char *data) #endif } -static int do_send_fragment(struct ipw_hardware *hw, unsigned char *data, +static void do_send_fragment(struct ipw_hardware *hw, unsigned char *data, unsigned length) { unsigned i; unsigned long flags; start_timing(); - - if (length == 0) - return 0; - - if (length > hw->ll_mtu) - return -1; + BUG_ON(length > hw->ll_mtu); if (ipwireless_debug) dump_data_bytes("send", data, length); @@ -458,11 +453,9 @@ static int do_send_fragment(struct ipw_hardware *hw, unsigned char *data, spin_unlock_irqrestore(&hw->lock, flags); end_write_timing(length); - - return 0; } -static int do_send_packet(struct ipw_hardware *hw, struct ipw_tx_packet *packet) +static void do_send_packet(struct ipw_hardware *hw, struct ipw_tx_packet *packet) { unsigned short fragment_data_len; unsigned short data_left = packet->length - packet->offset; @@ -522,8 +515,6 @@ static int do_send_packet(struct ipw_hardware *hw, struct ipw_tx_packet *packet) packet->length); kfree(packet); } - - return 0; } static void ipw_setup_hardware(struct ipw_hardware *hw) -- 2.39.5
