A note on sparse:
According to https://lwn.net/Articles/109066/ there are things
that sparse can't cope with. In particular, pm_clk_op_lock() and
pm_clk_op_unlock() may or may not lock/unlock psd->lock depending on
some runtime condition. To work around that we tell sparse the lock
is always untaken for the purpose of static analisys.

It looks like sparse is still complaining:

Would you happen to still have one of those randconfig configuration?

I'd like to know why sparse complains about 3 out of 93 configs.
