rtc: use boolean values with device_init_wakeup()

2025-01-09T17:29:24+00:00

device_init_wakeup() second argument is a bool type. Use proper boolean values when calling it to match the type and to produce unambiguous code which is easier to understand.

rtc: rk808: reduce 'struct rk808' usage

2022-12-11T19:56:33+00:00

Reduce usage of 'struct rk808' (driver data of the parent MFD), so that only the chip variant field is still being accessed directly. This allows restructuring the MFD driver to support SPI based PMICs.

rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12+00:00

rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

rtc: Remove dev_err() usage after platform_get_irq()

2019-08-13T08:53:10+00:00

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).
