Subject: Re: [patch 06/20] drivers/tty/metag_da: Initialize timer as pinned

I know it's not related to this patch, but it'd be nice to, as you're
changing the api name anyway, make a mod_pinned_relative() so that
more direct users of jiffies can go away...
or even better, mod_pinned_relative_ms() so that these drivers also do
not need to care about HZ.
