"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-987313 advisory.

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

    ath11k: mhi: use mhi_sync_power_up()

    If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The
    reason for that was that we were using mhi_async_power_up() which does not
    check any errors. But mhi_sync_power_up() on the other hand does check for
    errors so let's use that to fix the crash.

    I was not able to find a reason why an async version was used.
    ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from
    ath11k_hif_power_up(), which can sleep. So sync version should be safe to use
    here.
