Subject: [PATCH] ip2: use newer pci_get functions
Date: Mon, 25 Sep 2006 23:37:32 +0100 [thread overview]
Message-ID: <1159223852.11049.158.camel@localhost.localdomain> (raw)
This is one of a series of patches I plan to gradually trickle into the
tree which eliminates almost all remaining use of pci_find_* and lets me
build a pci_find_* free kernel for all but some obscure ISDN and SCSI
drivers. This is important as all pci_find_* users are not hotplug safe
- even if they are not the device being plugged.
