From 7b505627568c088b364705a86234fa1f2beb01b9 Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Mon, 27 Sep 2021 15:01:49 -0700 Subject: [PATCH] pktcdvd: add error handling support for add_disk() We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. The out_mem2 error label already does what we need so re-use that.
