From: Rafael J. Wysocki Date: Thu, 26 Oct 2017 10:12:16 +0000 (+0200) Subject: PCI / PM: Drop unnecessary invocations of pcibios_pm_ops callbacks X-Git-Tag: v4.15-rc1~145^2~1^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=302666d8a55ce7eb5fb0bd9fbd9437d74e0ce77c;p=thirdparty%2Fkernel%2Flinux.git PCI / PM: Drop unnecessary invocations of pcibios_pm_ops callbacks The only user of non-empty pcibios_pm_ops is s390 and it only uses "noirq" callbacks, so drop the invocations of the other pcibios_pm_ops callbacks from the PCI PM code. That will allow subsequent changes to be somewhat simpler. Signed-off-by: Rafael J.
