[PATCH 5.10 138/142] ASoC: topology: Fix memory corruption in soc_tplg_denum_create_values()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpen...@oracle.com>

commit 543466ef3571069b8eb13a8ff7c7cfc8d8a75c43 upstream.

The allocation uses sizeof(u32) when it should use sizeof(unsigned long)
so it leads to memory corruption later in the function when the data is
initialized.
