Hi, static analysis with Coverity has detected an issues in the rtl8723bs wifi driver: File: drivers/staging/rtl8723bs/os_dep/ioctl_linux.c in function rtw_dbg_port(): CID 18480: Operands don't affect result (CONSTANT_EXPRESSION_RESULT) dead_error_condition: The condition (extra_arg & 7U) > 7U cannot be true. if ((extra_arg & 0x07) > 0x07) padapter->driver_ampdu_spacing = 0xFF; else padapter->driver_ampdu_spacing = extra_arg; I'm not sure if the mask is (in)correct or the value it is being compared to 0x07 is (in)correct (or both!)
