* rtlwifi: rtl8192ce: rtl8192cu: Fix multiple def errors for allyesconfig buildLarry Finger2011-02-2313-102/+88
| | | | | | | | | | | | | | | | | | | As noted by Stephan Rothwell, an allyesconfig build fails since rtl8192cu was merged with failures such as: drivers/net/wireless/rtlwifi/rtl8192cu/built-in.o: In function `rtl92c_phy_sw_chnl': (.opd+0xf30): multiple definition of `rtl92c_phy_sw_chnl' drivers/net/wireless/rtlwifi/rtl8192ce/built-in.o:(.opd+0xb70): first defined here drivers/net/wireless/rtlwifi/rtl8192cu/built-in.o: In function `rtl92c_fill_h2c_cmd': (.opd+0x288): multiple definition of `rtl92c_fill_h2c_cmd' drivers/net/wireless/rtlwifi/rtl8192ce/built-in.o:(.opd+0x288): first defined here These are caused because the code shared between rtl8192ce and rtl8192cu is included in both drivers. This has been fixed by creating a new modue that contains the shared code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
