From e6a54d6f221301347aaf9d83bb1f23129325c1c5 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Thu, 23 Sep 2021 21:12:53 +0300 Subject: qed: Don't ignore devlink allocation failures devlink is a software interface that doesn't depend on any hardware capabilities. The failure in SW means memory issues, wrong parameters, programmer error e.t.c. Like any other such interface in the kernel, the returned status of devlink APIs should be checked and propagated further and not ignored.
