Subject: [PATCH AUTOSEL 5.4 10/31] isdn: mISDN: netjet: Fix crash in nj_probe:
Date: Thu,  3 Jun 2021 13:08:58 -0400	[thread overview]
Message-ID: <20210603170919.3169112-10-sashal@kernel.org> (raw)
In-Reply-To: <20210603170919.3169112-1-sashal@kernel.org>

From: Zheyu Ma <zheyuma97@gmail.com>

[ Upstream commit 9f6f852550d0e1b7735651228116ae9d300f69b3 ]

'nj_setup' in netjet.c might fail with -EIO and in this case
'card->irq' is initialized and is bigger than zero. A subsequent call to
'nj_release' will free the irq that has not been requested.

Fix this bug by deleting the previous assignment to 'card->irq' and just
keep the assignment before 'request_irq'.

The KASAN's log reveals it:
