Re: 2.6.15-rc5-mm2

Hi Andrew,

the following patch fixes the issues in
s390-introduce-struct-channel_subsystem.patch and
s390-convert-proc-cio_ignore.patch.

s390: Fix missing release function and cosmetic changes.

- Use kzalloc() in blacklist.c.
- Kill unwanted casts in blacklist.c.
- Provide release function for struct channel_subsystem.
