Subject: [PATCH v1 0/1] regulator: da9211: Fix crash when irqs are pre-enabled
Date: Thu, 24 Nov 2022 17:45:30 +0100	[thread overview]
Message-ID: <20221124-da9211-v1-0-a54549aa6d3b@chromium.org> (raw)

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.
