True, but that seems counter style for most uses of snd_ctl_enum_info
$ git grep -w snd_ctl_enum_info | grep -v ARRAY_SIZE | wc -l
159
$ git grep -w snd_ctl_enum_info | grep ARRAY_SIZE | wc -l
10
but most of those seem to choose variable amounts of a single
array. Here, ARRAY_SIZE seems better to me too.
For another real nitpick, please prefer "const *" over "const*"
$ git grep -P "\*\s+const\b" | wc -l
7068
$ git grep -P "\*const\b" | wc -l
1801
