Hi Andrew,
This patch addresses concerns raised by CCed people
regarding my previous patch which you added to mm yesterday.
On Monday 10 April 2006 17:22, Justin T. Gibbs wrote:

In light of this I did the following:
* moved inlines into aic79xx_core.c and aic7xxx_core.c
* fixed bug in ahd_delay (made it a trivial wrapper around udelay)
* fixed bug in aic7xxx_pci.c (wrong order of parameters
in ahc_pci_write_config calls)
* marked a few functions static
* spelling fix in error message
Patch which does s/__inline/inline/g will follow in a few minutes.

Won't apply t your tree because I failed to notice that you
already included those two small fixes.
Rediffed patch (which hopefully will apply) is attached. Sorry.
> Patch which does s/__inline/inline/g will follow in a few minutes.
This one (which I already sent) should apply.

I dropped everything except for aic7xxx-ahc_pci_write_config-fix.patch.
So please resend all patches from scratch. Preferably with accurate
Subject:s and with standalone changelogs, thanks.
