Subject: [PATCH v2 01/17] regmap-irq: Use sub_irq_reg() to calculate unmask register address
Date: Tue, 7 Jun 2022 16:53:08 +0100 [thread overview]
Message-ID: <20220607155324.118102-2-aidanmacdonald.0x0@gmail.com> (raw)
In-Reply-To: <20220607155324.118102-1-aidanmacdonald.0x0@gmail.com>
Call sub_irq_reg() instead of calculating the offset of the register
to avoid relying on the fact that sub_irq_reg() is a linear function.
This prepares for allowing drivers to override the default sub_irq_reg
implementation if the default behavior is unsuitable.
