Subject: [PATCH v3 02/19] irqdomain: Drop dead domain-name assignment
Date: Fri,  9 Dec 2022 15:01:33 +0100	[thread overview]
Message-ID: <20221209140150.1453-3-johan+linaro@kernel.org> (raw)
In-Reply-To: <20221209140150.1453-1-johan+linaro@kernel.org>

Since commit d59f6617eef0 ("genirq: Allow fwnode to carry name
information only") an IRQ domain is always given a name during
allocation (e.g. used for the debugfs entry).

Drop the leftover name assignment when allocating the first IRQ.
