The output of 
    git grep BT_AUTO_REPORT_ONLY_8192E_2ANT next-20140430

is
    next-20140430:drivers/staging/rtl8821ae/btcoexist/halbtc8192e2ant.c:#if (BT_AUTO_REPORT_ONLY_8192E_2ANT == 1)
    next-20140430:drivers/staging/rtl8821ae/btcoexist/halbtc8192e2ant.c:#if (BT_AUTO_REPORT_ONLY_8192E_2ANT == 0)
    next-20140430:drivers/staging/rtl8821ae/btcoexist/halbtc8192e2ant.c:#if (BT_AUTO_REPORT_ONLY_8192E_2ANT == 0)
    next-20140430:drivers/staging/rtl8821ae/btcoexist/halbtc8192e2ant.h:#define     BT_AUTO_REPORT_ONLY_8192E_2ANT                  0

So it seems that some trivial cleaning up is possible. Ie, drop the
#define and drop the three tests that are either always true or always
false. Is there a reason not to do that cleaning up?
