mfd: as3722: Fix wakeup source leaks on device unbind

2025-05-23T07:49:07+00:00

Device can be unbound, so driver must also release memory for the wakeup source. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250406-mfd-device-wakekup-leak-v1-2-318e14bdba0a@linaro.org Signed-off-by: Lee Jones

mfd: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-07-04T16:08:02+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

mfd: as3722: Convert to use maple tree register cache

2024-02-23T14:58:03+00:00

The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

mfd: Switch i2c drivers back to use .probe()

2023-06-15T08:19:37+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

mfd: as3722: Convert to i2c's .probe_new()

2022-12-07T13:27:20+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-421-uwe@kleine-koenig.org

mfd: as3722: Use devm_mfd_add_devices and devm_regmap_add_irq_chip

Use devm_mfd_add_devices() for adding MFD child devices and devm_regmap_add_irq_chip() for IRQ chip registration. This reduces the error code path and .remove callback for removing MFD child devices and deleting IRQ chip data. Signed-off-by: Laxman Dewangan Signed-off-by: Lee Jones

mfd: as3722: Mark PM functions as __maybe_unused

2016-01-11T06:23:43+00:00

The newly introduced as3722_i2c_suspend/resume functions are built unconditionally, but only used when power management is enabled, so we get a warning otherwise: drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function] drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function] This marks them both as __maybe_unused, which avoids an ugly #ifdef and gives us best compile-time coverage. When they are unused, the compiler will silently drop the functions from its output.
