Hi Dmitry,

Thanks for the feedback and the patch.  I've got just one question, 
included below, with a bunch of snipping).

Um, OK.  Previously patch feedback suggested to use bool instead of u8 
for single bit fields (see here: 
http://www.spinics.net/lists/linux-input/msg22198.html).  So I'm a

confirmation that it is really what we should do.
