[PATCH net-next 2/5] net: ipa: don't report EPROBE_DEFER error

From: Alex Elder
Date: Wed Feb 10 2021 - 17:35:55 EST


When initializing the IPA core clock and interconnects, it's
possible we'll get an EPROBE_DEFER error. This isn't really an
error, it's just means we need to be re-probed later.

Check the return code when initializing these, and if it's
EPROBE_DEFER, skip printing the error message.
