Subject: [PATCH v3 net-next 2/5] net: ipa: use dev_err_probe() in ipa_clock.c

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.

Use dev_err_probe() to report the error rather than dev_err().
This avoids polluting the log with these "error" messages.

Signed-off-by: Alex Elder <elder@...aro.org>

v3: - Use dev_err_probe(), as suggested by Heiner Kallweit.
v2: - Update copyright.
