Hi all.

I'm working on euduplula challenge (It is a series of programming
exercises for amateur linux kernel developers).  As an exercise i
decided to improve driver for speakup. First I'm going to fix checkpatch
warnings in driver.

In attachment you can find a patch that fixes two types of warning:
WARNING: Block comments use a trailing */ on a separate line
WARNING: Block comments use * on subsequent lines

I hope with your guidance i can improve speakup driver a bit.

Sincerely yours, Aleksey.

P.S. I'm not sure if I'm writing to a correct mailing list. If i'm
mistaken, could you please point me a correct mail list for discussion
about speakup driver.

Subject: [PATCH] staging: speakup: Fix warning about block comment

This patch fixes the checkpatch.pl warnings:
WARNING: Block comments use a trailing */ on a separate line
WARNING: Block comments use * on subsequent lines

All checkpatch warnings about comment in driver/staging/speakup/* are
fixed.
