[PATCH] drm/kmb: Use common error handling code in kmb_probe()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 3 Oct 2024 13:20:05 +0200

Add a label so that a bit of exception handling can be better reused
in a subsequent if branch of this function implementation.

This issue was detected by using the Coccinelle software.
