2019-10-11dmaengine: uniphier-mdmac: use devm_platform_ioremap_resource()Masahiro Yamada1-3/+1
Replace the chain of platform_get_resource() and devm_ioremap_resource() with devm_platform_ioremap_resource(). This allows to remove the local variable for (struct resource *), and have one function call less.

2019-07-31dmaengine: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-4/+1
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).
