[PATCH] remoteproc: qcom: q6v5-mss: Use common error handling code in q6v5_mpss_load()

From: Markus Elfring
Date: Tue Sep 24 2024 - 10:09:02 EST


From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

Add jump targets so that a bit of exception handling can be better reused
at the end of this function implementation.
