[PATCH 1/3] ASoC: simple-card: Use devm_kcalloc() in asoc_simple_card_parse_aux_devs()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
