Subject: i2c-piix4: Drop redundant PCI function number check
X-Git-Tag: v2.6.25-rc1~1189
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9b7389c0edb94a2623f21a6ac90afae63f201e73;p=platform%2Fkernel%2Flinux-3.10.git

i2c-piix4: Drop redundant PCI function number check

Checking the PCI function number doesn't add any value, and it makes
adding dynamic IDs to the driver more difficult. Drop this check.
