Subject: [PATCH] ip2: use newer pci_get functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1aff0ecafb5e94515dc37849fd32a810554f34f4;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] ip2: use newer pci_get functions

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.
