Thanks for the report. I checked how the equivalent function for cpufreq works
and as I tought it does fail the thing to write exceed PAGE_SIZE. I sent a
patch upstream that fix the missing check.
sysfs stuff is ABI so moving this to debugfs is a no go (due to we don't break
userspace rule) so this is the only solution currently.
If accepted, it will be queued for stable backport.
