    ath9k_hw: make bluetooth coexistence support optional at compile time · 8a309305
    Felix Fietkau authored
    Many systems (e.g. embedded systems) do not have wifi modules connected to
    bluetooth modules, so bluetooth coexistence is irrelevant there. With the
    addition of MCI support, ath9k picked up quite a bit of extra code that
    can be compiled out this way.
    
    This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
    querying the bluetooth coexistence scheme, allowing the compiler to
    eliminate code that uses it, with only very little use of #ifdef.
    
    On MIPS this reduces the total size for the modules by about 20k.
