Stop spamming the logs with errors about missing mechanism for setting the so called download (or dump) mode for users that have not requested that feature to be enabled in the first place.

This avoids the follow error being logged on boot as well as on shutdown when the feature it not available and download mode has not been enabled on the kernel command line:

qcom_scm firmware:scm: No available mechanism for setting download mode

Fixes: 79cb2cb8d89b ("firmware: qcom: scm: Disable SDI and write no dump to dump mode") Fixes: 781d32d1c970 ("firmware: qcom_scm: Clear download bit during reboot") Cc: Mukesh Ojha quic_mojha@quicinc.com Cc: stable@vger.kernel.org # 6.4 Signed-off-by: Johan Hovold johan+linaro@kernel.org Reviewed-by: Mukesh Ojha quic_mojha@quicinc.com Link: https://lore.kernel.org/r/20241002100122.18809-2-johan+linaro@kernel.org Signed-off-by: Bjorn Andersson andersson@kernel.org
