Summary
regulator: da9211: Use irq handler when ready
Details

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

regulator: da9211: Use irq handler when ready

If the system does not come from reset (like when it is kexec()), the regulator might have an IRQ waiting for us.

If we enable the IRQ handler before its structures are ready, we crash.

This patch fixes:
