That only happens to be case because MSR_INFRA | MSR_ADHOC == MSR_AP. This
seems to be the intent:

    #define MSR_MASK 0x03
    if ((bt_msr & MSR_MASK) == MSR_AP)

In rtl8192se, there are also MSR_LINK_... constants covering MSR_...
and in addition, there is a MSR_LINK_MASK. These macros are quite
redundant though given the other definitions, but the mask is still
nice to have I guess.

Also, personally I would submit just one patch touching all drivers, but
I see that Rickard has submitted a bunch of patches (without cover letter
either, making it more difficult to group them). What would you prefer,
a single patch touching multiple drivers (as the changes are mostly the
same) or split patches?

Kind regards,
Peter
