CVE-2024-46846

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: rockchip: Resolve unbalanced runtime PM / system PM handling<br /> <br /> Commit e882575efc77 ("spi: rockchip: Suspend and resume the bus during<br /> NOIRQ_SYSTEM_SLEEP_PM ops") stopped respecting runtime PM status and<br /> simply disabled clocks unconditionally when suspending the system. This<br /> causes problems when the device is already runtime suspended when we go<br /> to sleep -- in which case we double-disable clocks and produce a<br /> WARNing.<br /> <br /> Switch back to pm_runtime_force_{suspend,resume}(), because that still<br /> seems like the right thing to do, and the aforementioned commit makes no<br /> explanation why it stopped using it.<br /> <br /> Also, refactor some of the resume() error handling, because it&amp;#39;s not<br /> actually a good idea to re-disable clocks on failure.
