Subject[patch] ASoC: Intel: do cast earlier in sst_cdev_tstamp()
My static checker complains about these because it looks like the
multiply can overflow and then we cast to a larger data type. I don't
think this is a problem, but it's also harmless to do the cast earlier
so let's silence the static checker warning.
