Subject: PM / suspend: Print debug messages for device using direct-complete
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4a0fa9f9fdb5a7230da6fb250c270c01d5f21fb5;p=openwrt%2Fstaging%2Fblogic.git

PM / suspend: Print debug messages for device using direct-complete

Devices using the direct-complete optimization are not present it
debug messages printed by the core device suspend and resume code,
which sometimes makes it difficult to diagnose problems related to
them, so add debug messages for those devices.
