Subject: [PATCH v3 04/13] cxl/mem: Fix cxl_mem_probe() error exit
Date: Wed, 18 May 2022 16:34:31 -0700	[thread overview]
Message-ID: <165291687176.1426646.15449254938752532784.stgit@dwillia2-xfh> (raw)
In-Reply-To: <165291684910.1426646.8615474651213855015.stgit@dwillia2-xfh>

The addition of cxl_mem_active() broke error exit scenarios for
cxl_mem_probe(). Return early rather than proceed with disabling
suspend, and update the label name since it is no longer a terminal
"out" label that exits the function.

Fixes: 9ea4dcf49878 ("PM: CXL: Disable suspend")
