Subject: realtek: fix SMP startup
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2b12da1313706cdd14791f329899de11ce9a35eb;p=openwrt%2Fstaging%2Fxback.git

realtek: fix SMP startup

The scope of the SMP startup structure is wrong. It is created on the
stack and not as a global variable. This can lead to startup failures.

Fixes: 3f41360eb70c ("realtek: use upstream recommendation for CPU start")
