Subject: [PATCH] ALSA: emu10k1: Rate-limit error messages about page errors
Git-commit: 11d42c81036324697d367600bfc16f6dd37636fd
Patch-mainline: v4.18-rc1
References: bsc#1051510

The error messages at sanity checks of memory pages tend to repeat too
many times once when it hits, and without the rate limit, it may flood
and become unreadable.  Replace such messages with the *_ratelimited()
variant.
