I added returns for failures .. I would hope that this doesn't break anything in

Hows that Alan?
Fixes the following warning,
drivers/ide/ide-tape.c: In function 'idetape_copy_stage_from_user':
drivers/ide/ide-tape.c:2662: warning: ignoring return value of 'copy_from_user', declared with attribute warn_unused_result
drivers/ide/ide-tape.c: In function 'idetape_copy_stage_to_user':
drivers/ide/ide-tape.c:2689: warning: ignoring return value of 'copy_to_user', declared with attribute warn_unused_result
I've been down the road of trying to fix that code as well a while back.
Although my patches had flaws and didn't go in, perhaps your current
attempt could bennefit by looking at what I tried to do back then and
the feedback I recieved, so I thought I'd point them out to you.
Take a look at the two threads named "[PATCH] ide-tape: attempt to
handle copy_*_user() failures" and "[PATCH] ide-tape: attempt to
handle copy_*_user() failures [take two]"
Here's a link to them in the archives :
