Subject: [PATCH] firmware/psci: demote suspend-mode warning to debug level
Date: Mon, 24 Oct 2022 16:34:17 +0200 [thread overview]
Message-ID: <20221024143417.11463-1-johan+linaro@kernel.org> (raw)
On some Qualcomm platform, like SC8280XP, the attempt to set PC mode
during boot fails with PSCI_RET_DENIED and since commit 998fcd001feb
("firmware/psci: Print a warning if PSCI doesn't accept PC mode") this
is now logged at warning level:
psci: failed to set PC mode: -3
As there is nothing users can do about the firmware behaving this way,
demote the warning to debug level.
Signed-off-by: Johan Hovold <johan+linaro@kernel.org>

Note that a separate change to the cpuidle driver will start logging the
mode actually used:
