Subject: [PATCH 5.10 193/215] coresight: Propagate symlink failure

From: Jeremy Linton <jeremy.linton@....com>

commit 51dd19a7e9f8fbbb7cd92b8a357091911eae7f78 upstream.

If the symlink is unable to be created, the driver goes
ahead and continues device creation. Instead lets propagate
the failure, and fail the probe.
