Subject: [PATCH 3.18 13/31] scsi: vmw_pscsi: Rearrange code to avoid multiple calls to free_irq during unload
Date: Thu, 20 Dec 2018 10:18:25 +0100 [thread overview]
Message-ID: <20181220085743.129116012@linuxfoundation.org> (raw)
In-Reply-To: <20181220085742.601260254@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 02f425f811cefcc4d325d7a72272651e622dc97e ]
Currently pvscsi_remove calls free_irq more than once as
pvscsi_release_resources and __pvscsi_shutdown both call
pvscsi_shutdown_intr. This results in a 'Trying to free already-free IRQ'
warning and stack trace. To solve the problem pvscsi_shutdown_intr has been
moved out of pvscsi_release_resources.
