These don't need to be changed and base should in fact be unsigned long
for portability.

Other little changes
Move some code from one place to another.
Get rid of ugly ifdefs in code in next p[patches, so here create functions
and macros to enable it.
Rename some functions and align some code to 80 chars.

From: Jiri Slaby @ 2005-10-09 19:42 UTC (permalink / raw)
To: Andrew Morton; +Cc: Linux Kernel Mailing List, Greg KH
Pci probing added
Pci probing functions added, most of functions rewrited because od it (some
for cycles are redundant).
Used PCI_DEVICE macro.
Generated in 2.6.14-rc2-mm2 kernel version

What is this "struct device" used for? You do not need it.

For all of your printk() calls, please use dev_dbg() or dev_warn() or
the other dev_* calls please.

Register the firmware request for when you see the device that needs it,
in your probe function, not in your module init function.
Hope this helps,

More whitespaces and coding style
Wrap all the code to 80 chars on a line.
Some `}\nelse' changed to `} else'.
Clean whitespaces in header file.
Generated in 2.6.14-rc2-mm2 kernel version

I am sorry but do you really consider the new form more readable?
