Subject: [PATCH AUTOSEL 5.15 1/5] ASoC: imx-card: Adjust over allocation of memory in imx_card_parse_of()

From: Chenyuan Yang <chenyuan0y@...il.com>

[ Upstream commit a9a69c3b38c89d7992fb53db4abb19104b531d32 ]

Incorrect types are used as sizeof() arguments in devm_kcalloc().
It should be sizeof(dai_link_data) for link_data instead of
sizeof(snd_soc_dai_link).

This is found by our static analysis tool.
