From df66617bfe87487190a60783d26175b65d2502ce Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Tue, 9 Mar 2021 19:30:17 -0800 Subject: [PATCH] block: rsxx: fix error return code of rsxx_pci_probe() When create_singlethread_workqueue returns NULL to card->event_wq, no error return code of rsxx_pci_probe() is assigned. To fix this bug, st is assigned with -ENOMEM in this case.
