Subject: [PATCH 4/4] x86/mce: remove redundant call to irq_work_queue()
Date: Wed, 18 Nov 2020 15:15:52 +0000	[thread overview]
Message-ID: <20201118151552.1412-5-gabriele.paoloni@intel.com> (raw)
In-Reply-To: <20201118151552.1412-1-gabriele.paoloni@intel.com>

Right now in do_machine_check() we have:
__mc_scan_banks()->mce_log()->irq_work_queue(&mce_irq_work)

hence the call of irq_work_queue() below after __mc_scan_banks()
seems redundant. Just remove it.
