Hello Larry Finger,
The patch 21e4b0726dc6: "rtlwifi: rtl8821ae: Move driver from staging
to regular tree" from Sep 22, 2014, leads to the following static
checker warning:
drivers/net/wireless/rtlwifi/rtl8821ae/hw.c:2183 _rtl8821ae_set_media_status()
warn: masked condition is always false. '(bt_msr & 252) == 3'
drivers/net/wireless/rtlwifi/rtl8821ae/hw.c
2181 rtl_write_byte(rtlpriv, MSR, bt_msr);
2182 rtlpriv->cfg->ops->led_control(hw, ledaction);
2183 if ((bt_msr & 0xfc) == MSR_AP)
^^^^^^^^^^^^^^^^^^^^^^^^^
This condition is never true. We mask out the 0xfc flags at the
beginning of the function. MSR_AP is 0x3.
2184 rtl_write_byte(rtlpriv, REG_BCNTCFG + 1, 0x00);
2185 else
2186 rtl_write_byte(rtlpriv, REG_BCNTCFG + 1, 0x66);
2187
2188 return 0;
2189 }
regards,
dan carpenter
