Subject: [PATCH v13 RESEND 1/2] mfd: madera: Add irqchip data pointer into struct madera
Date: Tue, 16 Oct 2018 10:38:38 +0100	[thread overview]
Message-ID: <20181016093839.6258-2-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20181016093839.6258-1-rf@opensource.cirrus.com>

Put the pointer to struct regmap_irq_chip_data into the parent
mfd structure so that the child irqchip driver does not need
a trivial private structure to store only this pointer. As
the irqchip child driver already has a pointer to the parent
struct madera it can use that to store the pointer. This also
means that the irqchip driver does not need a double-indirection
from its local struct to get at the parent struct madera.
