From: Glen Lee Date: Fri, 11 Sep 2015 03:04:20 +0000 (+0900) Subject: staging: wilc1000: coreconfigurator.c: remove unused functions X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5da0a0706b4d2a591cf9dcb0e9bfe0100bf5a5b2;p=linux-beck.git staging: wilc1000: coreconfigurator.c: remove unused functions This patch removes following unused funtions which will not be used anymore. ascii_hex_to_dec get_hex_char extract_mac_addr create_mac_addr conv_ip_to_int conv_int_to_ip get_wid_type get_type CreateConfigPacket ConfigWaitResponse ConfigProvideResponse ConfigPktReceived ParseWriteResponse CreatePacketHeader ParseResponse ProcessBinWid ProcessAdrWid ProcessStrWid ProcessIPwid ProcessIntWid ProcessShortWid ProcessCharWid As a result, four global variable causes defined but not used compile warnings. So just remove unused varialbs g_seqno, g_wid_num, Res_Len and g_oper_mode.
