Subject: [patch v6 5/7] genirq/affinity: Remove the leftovers of the original set support
Date: Sat, 16 Feb 2019 18:13:11 +0100 [thread overview]
Message-ID: <20190216172228.689834224@linutronix.de> (raw)
In-Reply-To: 20190216171306.403545970@linutronix.de
Now that the NVME driver is converted over to the calc_set() callback, the
workarounds of the original set support can be removed.
