[PATCH] I2O: Bugfixes
- Removed some kmalloc's with __GFP_ZERO and replace it with memset() because it didn't work properly. - Fixed returned message frame in i2o_cfg_passthru() which caused raidutils to display wrong error message in case a disk was missing. - Fixed size of printk() in i2o_scsi.c. - Fixed get_device() and put_device() in probing of the I2O controller.
