Subject: [PATCH] spi: Return deferred probe error when controller isn't yet available
Git-commit: 9c22ec4ac27bcc5a54dd406da168f403327a5b55
Patch-mainline: v6.0-rc1
References: bsc#1203699
If the controller is not available, it might be in the future and
we would like to re-probe the peripheral again. For that purpose
return deferred probe.
