ASoC: rt298: Make rt298_index_def const
The index_cache is per instance run time state but rt298_index_def is not. Make rt298_index_def const and make a copy of memory for index_cache rather than directly use the rt298_index_def. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
