Official description

In the Linux kernel, the following vulnerability has been resolved: PM: domains: Fix sleep-in-atomic bug caused by genpd_debug_remove() When a genpd with GENPD_FLAG_IRQ_SAFE gets removed, the following sleep-in-atomic bug will be seen, as genpd_debug_remove() will be called with a spinlock being held.
