That commit isn't in -next and this change to add a return
value to no_printk in _this_ patch is, as I wrote, not
required here.

It's fine that no_printk return a 0 value, but it should
be introduced in a separate patch that introduces that
requirement or at least mentioned in the changelog of
this patch _why_ it's it to be changed.  Otherwise, the
change just appears spurious.
