Subject: screen_artist: fix compilation errors
X-Git-Tag: v0.12_alpha1~260
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=260eb4ea969988190695386f7f7d6cc237c2b17d;p=ncmpc.git

screen_artist: fix compilation errors

Unfortunately when I fixed the GCC warnings and refactored lots of the
code, the "artist" screen was disabled.  This patch applies all API
changes and fixes all warnings.
