Subject: Re: [PATCH 2/4] input: keyboard/mouse/touchscreen/misc: Use dev_get_drvdata()

I am not an expert on this. I just write a coccinelle script to search
this kind of misuse and fix it in a naive way.
Could you tell me about how to use the proper bus accessors? Then I
will fix it up and resend a v2 patch set.

Thanks.
