Subject: soc: ti: qmss: fix the case when !SMP
X-Git-Tag: v4.10-rc1~86^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=920f8bf7f366ed20935669f782ffcb5a36d5df8f;p=thirdparty%2Flinux.git

soc: ti: qmss: fix the case when !SMP

The irq_set_affinity_hint() will always fail when !SMP and
Networking will fail on Keystone 2 devices in this case.
Hence, fix by ignoring IRQ affinity settings when !SMP.
