From 27a7805a19a7422c2a0ea222bcd14e5258f5fdc3 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Tue, 12 Jul 2022 22:20:41 -0700 Subject: [PATCH] scsi: qla2xxx: Fix imbalance vha->vref_count commit 63fa7f2644b4b48e1913af33092c044bf48e9321 upstream. vref_count took an extra decrement in the task management path. Add an extra ref count to compensate the imbalance.
