It does seem > strange to me, as the makros are the same as in rtl2830_priv.h Are you using some old version of checkpatch.pl ? Mine is: commit c06a9ebdb7a4f4823d4225fe789d8c20a1d534eb Author: Joe Perches Date: Mon Apr 16 13:35:11 2012 -0600 If you are using older version then upgrade. checkpatch.pl is developed very rapidly and there is all the time new checks. regards Antti -- http://palosaari.fi/
