cciss updates July 19, 2010

The following series implements mostly cleanups to the initialization code in cciss along the same lines as what's already been done in hpsa.

There are also a few bug fixes. The SCSI tape code was not setting the performant mode bits in commands, which caused a hang. The code to reset controllers via PCI power management methods only works on old controllers, so an alternate method is used for newer controllers.

There are a couple of big patches to make cciss use more consistent variable names (always h for hba, and c for command, rather than a mishmash of various things names) and to generally use dev_warn, etc. instead of printk.

These patches apply to the 'for-2.6.36' branch of Jens Axboe's git
tree: http://git.kernel.org/?p=linux/kernel/git/axboe/linux-2.6-block.git;a=summary
(there are many changes to cciss in that tree on which these patches depend.)
