Subject: Re: [PATCH 2/2] MEMSTICK: Add driver for Ricoh R5C592 Card reader.

I see two immediate problems with this patch:

1. On cosmetic level, custom debug macros should not be employed. Device
core already have this functionality (dynamic debug levels and such). Please,
use dev_dbg and friends for print-outs.

2. On a structural level, I'd rather prefer host drivers to not start their
own threads. If you look at both current host implementations, they operate
in callback fashion. Apart from saving some resources, this reduces the
amount of problems encountered during suspend/resume and shutdown.
