From e17be6e1b713f188728a23ebfba15546a025c109 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 30 Jul 2019 11:15:10 -0700 Subject: dmaengine: Remove dev_err() usage after platform_get_irq() 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. // @@ 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(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).
