Subject: [PATCH v2 01/14] gpio: Bulk conversion to generic_handle_domain_irq()
Date: Mon,  2 Aug 2021 17:26:17 +0100	[thread overview]
Message-ID: <20210802162630.2219813-2-maz@kernel.org> (raw)
In-Reply-To: <20210802162630.2219813-1-maz@kernel.org>

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().
