HSI: omap_ssi_port: Drop error checking for debugfs_create_dir

2023-05-27T16:50:27Z

This patch fixes the error checking in omap_ssi_port.c. The DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. Signed-off-by: Osama Muhammad Signed-off-by: Sebastian Reichel

HSI: Remove dev_err() usage after platform_get_irq()

2019-07-30T20:40:03Z

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).

HSI: omap_ssi_port: fix debugfs_simple_attr.cocci warnings

2019-02-14T11:36:21Z

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE for debugfs files. Semantic patch information: Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file() imposes some significant overhead as compared to DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().
