[PATCH v2] driver core: fw_devlink: Don't warn about sync_state() pending
Posted by Ulf Hansson 4 months ago 
Due to the wider deployment of the ->sync_state() support, for PM domains
for example, we are receiving reports about the sync_state() pending
message that is being logged in fw_devlink_dev_sync_state(). In particular
as it's printed at the warning level, which is questionable.

Even if it certainly is useful to know that the ->sync_state() condition
could not be met, there may be nothing wrong with it. For example, a driver
may be built as module and are still waiting to be initialized/probed. For
this reason let's move to the info level for now.

Changes in v2:
	- Due to discussions on v1 and because the default Kconfig is to use the
	FW_DEVLINK_SYNC_STATE_STRICT, I suggest that for now it may be best to
	keep the warning level for the "Timed out.." print and only change the
	"sync_state pending..." message.
