The new temporary variable is lacks a 'const' annotation:

sound/soc/generic/audio-graph-card.c:87:7: error: assigning to 'u32 *' (aka 'unsigned int *') from 'const void *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]

Fixes: c152f8491a8d ("ASoC: audio-graph-card: fix an use-after-free in graph_get_dai_id()")
