Subject: [PATCH 2.6.9-rc2-mm4 zr36120.c][5/8] Convert pci_find_device to pci_dev_present


The dev was not used from pci_find_device so it was acceptable to replace
with pci_dev_present. There was no need for it to be in a while loop originally.
Compile tested.

That code should die I think. All the tests it does are done in
pci/quirks.c and set up pci_pci_flags

The whole driver is CONFIG_BROKEN anyway... I only verified my changes
didn't add new compiler errors. What part should I remove? Just this check?

Thanks.

pci/quirks.c does these checks and sets the flags.
Replacing with a check for "pci_pci_problems & PCIPCI_TRITON" should do.

bttv does simliar things in bttv_check_chipset() (bttv-cards.c),
you might want to have a look there ...

Hi,

Thanks a lot for your help. Is this what you were thinking?
Ive compile tested it.
