Subject: netdev: set __percpu attribute on netdev_alloc_pcpu_stats
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=693350c2ffe42a21185070b1e8ab77959b45d61e;p=openwrt%2Fstaging%2Fblogic.git

netdev: set __percpu attribute on netdev_alloc_pcpu_stats

This patch fixes sparse warnings in vlan driver.
It propagates the sparse __percpu attribute from alloc_percpu
into netdev_alloc_pcpu_stats. I expect it may trigger additional
sparse warnings from other drivers that are missing the __percpu
attribute.
