From: Alex Williamson Date: Wed, 16 Sep 2015 04:24:46 +0000 (-0600) Subject: PCI: Use function 0 VPD for identical functions, regular VPD for others X-Git-Tag: omap-for-v4.3/fixes-rc5~89^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da2d03ea27f6ed9d2005a67b20dd021ddacf1e4d;p=pandora-kernel.git PCI: Use function 0 VPD for identical functions, regular VPD for others 932c435caba8 ("PCI: Add dev_flags bit to access VPD through function 0") added PCI_DEV_FLAGS_VPD_REF_F0. Previously, we set the flag on every non-zero function of quirked devices. If a function turned out to be different from function 0, i.e., it had a different class, vendor ID, or device ID, the flag remained set but we didn't make VPD accessible at all. Flip this around so we only set PCI_DEV_FLAGS_VPD_REF_F0 for functions that are identical to function 0, and allow regular VPD access for any other functions.
