CVE-2026-72260

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

ASoC: mediatek: mt8192: Check runtime resume during probe

The MT8192 AFE probe enables runtime PM temporarily while reinitializing
the regmap cache from hardware, but it uses pm_runtime_get_sync()
without checking the return value. If runtime resume fails, probe keeps
going without the device necessarily being accessible, and
pm_runtime_get_sync() may leave the PM usage count incremented.

The regmap_reinit_cache() failure path also returns before dropping the
temporary PM reference and before clearing pm_runtime_bypass_reg_ctl.

Use pm_runtime_resume_and_get() so resume failures do not leak a usage
count, and clear the temporary bypass flag after dropping the probe PM
reference on all regmap_reinit_cache() outcomes.
