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 <dsterba@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
