Subject: [PATCH AUTOSEL 4.19 17/32] ata: libahci: do not complain in case of deferred probe

From: Miquel Raynal <miquel.raynal@...tlin.com>

[ Upstream commit 090bb803708198e5ab6b0046398c7ed9f4d12d6b ]

Retrieving PHYs can defer the probe, do not spawn an error when
-EPROBE_DEFER is returned, it is normal behavior.

Fixes: b1a9edbda040 ("ata: libahci: allow to use multiple PHYs")
