drm/panthor: Fix NULL pointer dereference on panthor_fw_unplug

Noroxi assessment

Priority: Monitor (action score 22/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Linux Linux 920c6af98e98e6afedf6318a75bac95af8415c6c, aab8b8a42e206a399fe3a5ed4b4cbb45ff6c546c.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 920c6af98e98e6afedf6318a75bac95af8415c6c, aab8b8a42e206a399fe3a5ed4b4cbb45ff6c546c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix NULL pointer dereference on panthor_fw_unplug This patch removes the MCU halt and wait for halt procedures during panthor_fw_unplug() as the MCU can be in a variety of states or the FW may not even be loaded/initialized at all, the latter of which can lead to a NULL pointer dereference. It should be safe on unplug to just disable the MCU without waiting for it to halt as it may not be able to.
