After a provider\nunbind/rebind cycle (deferred-probe replay during early boot, real\nmodule unload of a clk driver that owns GDSCs, or an OF-overlay tear-\ndown) the next gdsc_init() will end up trying to re-register a name\nthat is still in the list and pm_genpd_init() returns -EEXIST.\n\nWhile we are here, flip the order so the consumer-facing OF provider\nentry is the first thing removed -- otherwise a fresh\nof_genpd_get_from_provider() call racing with the teardown could\nattach to a domain that is mid-removal.\n\nIterate the scs[] array and pm_genpd_remove() each registered domain\nafter the subdomain links are torn down. The regulators stay devm-\nmanaged (devm_regulator_get_optional() in gdsc_register()), so the\nrelease happens automatically when the underlying device is unbound;\njust the genpd accounting needs to be undone explicitly.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10 · no fix planned: Red Hat Enterprise Linux 10 · updated 2026-10-05 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-93145.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":216302,"id":"CVE-2026-93145","ts":1791274068997,"field":"cvss","old":null,"new":"5.5"},{"seq":216301,"id":"CVE-2026-93145","ts":1791274068997,"field":"severity","old":"none","new":"medium"}]}
