Subject: [PATCH 31/46] ASoC: pxa: ac97: use normal MMIO accessors
Date: Fri, 18 Oct 2019 17:41:46 +0200 [thread overview]
Message-ID: <20191018154201.1276638-31-arnd@arndb.de> (raw)
In-Reply-To: <20191018154052.1276506-1-arnd@arndb.de>
To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting
an __iomem pointer, and then using readl/writel on that.
Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
the code at the same time.

Subject: [PATCH 31/46] ASoC: pxa: ac97: use normal MMIO accessors
Date: Fri, 18 Oct 2019 17:41:46 +0200 [thread overview]
Message-ID: <20191018154201.1276638-31-arnd@arndb.de> (raw)
In-Reply-To: <20191018154052.1276506-1-arnd@arndb.de>
To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting
an __iomem pointer, and then using readl/writel on that.
Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
the code at the same time.
