This was the last of my pci __devinitdata patches!

So, this was the first set of my patches. :)
Things I learned:
- The default linelength of thunderbird (72 chars) are not enough for patches and configuring the mailclient can save a lot of time.

- There are many pci-drivers which are not conform in all points to
<kernel>/Documentation/pci.txt
e.g. : if the remove funcion of the driver is marked as __devexit,
the __devexit_p() is forgotten in struct pci_driver, which can leave a pointer to a function which doesn't exist. (evil)

- Bringing more ifdefs into the kernel is evil too.

- Typing 286 (what a number) times "__devinitdata" could have benn much more boring.

Questions I have:

- What is the prefered way to make powemanagement-stuff depend on CONFIG_PM?

	ifdef the .suspend and .resume in struct pci_driver and gather these functions into ONE
	#ifdef CONFIG_PM
	#endif
	?
	There are lots of drivers who have there PM-functions compiled, even if no CONFIG_PM is set.

- Will these patches be put into the mainline-kernel by you or must every janitor send them
again to the subsys-maintainer?

Greets,
Henne

Uh, yes, that's well-known. :(
I have written email about how I can use tbird successfully, or you can try this web page, although our recommendations are different:

Make a .config file with CONFIG_HOTPLUG=n (tricky[1]) and then build a kernel. The modpost phase will check/catch/warn about these. I have sent patches for quite a few of them recently.
