treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

Input: imx_keypad - use guard notation when acquiring mutex

2024-10-03T15:53:14Z

This makes the code more compact and error handling more robust by ensuring that mutexes are released in all code paths when control leaves critical section. Link: https://lore.kernel.org/r/20240825051627.2848495-7-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: imx_keypad - add missing linux/input.h include

2022-09-26T15:15:10Z

We are going to clean up matrix_keymap.h from unnecessary includes, so the driver needs to include API that it uses directly. Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20220923194738.927408-4-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov

Input: imx_keypad - convert to a DT-only driver

Input: remove dev_err() usage after platform_get_irq()

2019-08-14T17:49:01Z

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).

Input: imx_keypad - make sure keyboard can always wake up system

2019-06-12T00:52:02Z

There are several scenarios that keyboard can NOT wake up system from suspend, e.g., if a keyboard is depressed between system device suspend phase and device noirq suspend phase, the keyboard ISR will be called and both keyboard depress and release interrupts will be disabled, then keyboard will no longer be able to wake up system. Another scenario would be, if a keyboard is kept depressed, and then system goes into suspend, the expected behavior would be when keyboard is released, system will be waked up, but current implementation can NOT achieve that, because both depress and release interrupts are disabled in ISR, and the event check is still in progress. To fix these issues, need to make sure keyboard's depress or release interrupt is enabled after noirq device suspend phase, this patch moves the suspend/resume callback to noirq suspend/resume phase, and enable the corresponding interrupt according to current keyboard status.

Input: imx_keypad - use devm_platform_ioremap_resource() to simplify code

2019-05-21T05:45:17Z

Use the new helper devm_platform_ioremap_resource() which wraps the platform_get_resource() and devm_ioremap_resource() together, to simplify the code. Signed-off-by: Anson Huang Reviewed-by: Mukesh Ojha Signed-off-by: Dmitry Torokhov
