Subject: [PATCH] firmware: stratix10-svc: Fix an NULL vs IS_ERR() bug in probe
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: e1d6ca042e62c2a69513235f8629eb6e62ca79c5
[ Upstream commit e1d6ca042e62c2a69513235f8629eb6e62ca79c5 ]
The svc_create_memory_pool() function returns error pointers. It never
returns NULL. Fix the check.
