CVE-2026-31475

In the Linux kernel, the following vulnerability has been resolved:

ASoC: sma1307: fix double free of devm_kzalloc() memory

A previous change added NULL checks and cleanup for allocation
failures in sma1307_setting_loaded().

However, the cleanup for mode_set entries is wrong. Those entries are
allocated with devm_kzalloc(), so they are device-managed resources and
must not be freed with kfree(). Manually freeing them in the error path
can lead to a double free when devres later releases the same memory.

Drop the manual kfree() loop and let devres handle the cleanup.
