Subject: ASoC: rt286: Fix run time error while modifying const data
From: Axel Lin <axel.lin@xxxxxxxxxx>
commit dc6d84c69cf8296b1e8e2fd0b1e115b7787ef4e9 upstream.
Make a copy of memory for index_cache rather than directly use the
rt286_index_def to avoid run time error.
Fixes: c418a84a8c8f ("ASoC: Constify reg_default tables")
