tinyalsa: Fails to build with pcm_plugin.c:156:5: error: 'strncpy' specified bound 64 equals destination size [-Werror=stringop-truncation].

[dreirund]

Ahoj,

when I try to build tinyalsa from the handsomefeed feed, it fails with
pcm_plugin.c:156:5: error: 'strncpy' specified bound 64 equals destination size [-Werror=stringop-truncation].

After a failing make -j6, here the terminal output of
make -j1 V=sc package/feeds/handsomefeed/tinyalsa/compile:
