Subject: [PATCH 16/23] arch: alpha: use generic irq error counter
Date: Fri, 18 Dec 2020 15:57:39 +0100 [thread overview]
Message-ID: <20201218145746.24205-17-info@metux.net> (raw)
In-Reply-To: <20201218145746.24205-1-info@metux.net>
Use the newly introduced irq error counter, that's already maintained
by all callers of ack_bad_irq(), in order to remove duplicate code.
Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
