[PATCH v5 1/4] media: s5p-tv: Replace mxr_ macro by default dev_

Hello,
May I ask what is the rationale for this patch?
To reduce a few lines of code?
Or to give up possibility of changing message format in just one place?

I could see migrating from mxr_* to pr_* could seen as the fix, but not this.

Waiting for reply,
Tomasz Stanislawski
