+Subject: avr32: Fix cpufreq oops when ondemand governor is default
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fhskinnemoen%2Favr32-2.6.git;a=commitdiff_plain;h=f04d264afc51acdffeba9cdf3baf04116687680c

+avr32: Fix cpufreq oops when ondemand governor is default
+
+Move the AP7 cpufreq init to late_initcall() so that we don't try to
+bring up cpufreq until the governor is ready. x86 also uses
+late_initcall() for this.
