Subject: [PATCH v3 03/13] genirq: Employ ack_irq() and eoi_irq() where relevant
Date: Tue, 29 Jun 2021 13:50:00 +0100	[thread overview]
Message-ID: <20210629125010.458872-4-valentin.schneider@arm.com> (raw)
In-Reply-To: <20210629125010.458872-1-valentin.schneider@arm.com>

This can easily be coccinelle'd to replace all existing chip->irq_{ack,
eoi} callsites, however not all callsites benefit from this
replacement: fasteoi flow handlers for instance only deal with an
->irq_eoi() callback. Instead, only patch callsites that can benefit from
the added functionality.
