Ivan,

The following patch is suggested by the code-analysis tool cppcheck as the test 
is always false. As it will not affect STA usage, I have no way to test the 
change. Could you please do so?

Thanks,

Larry

Yes, compiling now, for some reason it doesn't apply cleanyl so I manualy 
changed this line.
And what exactly I should test?

Does it affect operation in AP mode? Before this change, the code always wrote 
0x66 to the register. Now it seems that it will write 0 if in AP mode. As I have 
no idea what that register does, I do not know what effect the change will have.

At the first look all works as before, I will test a few days and then report.
