Hi,

Sorry for the late reply.

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.

This patch changes handling of -EPROBE_DEFER in the modified drivers (most don't support it and error message will no longer be printed).

I cannot apply it as it is (seems that -EPROBE_DEFER handling should be audited/fixed in the affected drivers first).

// <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).
