| |
simplify function Hal_GetChnlGroup8723B(). It returns an unused and unnecessary bool value telling which band the device works on. Since we work only on 2.4Ghz band and the useful return value is the second function argument we convert the return type to void.
remove 5Ghz dead code either (for channel > 14).
