Subject: [PATCH] bootconfig: Fix missing return check of xbc_node_compose_key function
Date: Tue, 31 Aug 2021 00:32:56 -0300	[thread overview]
Message-ID: <> (raw)

The function `xbc_show_list should` handle the keys during the
composition. Even the errors returned by the compose function. Instead
of removing the `ret` variable, it should save the value and show the
exact error. This missing variable is causing a compilation issue also.
