mfd: max77620: Remove #ifdef guards for PM related functions

2022-12-07T13:28:12Z

Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

mfd: max77620: Convert to i2c's .probe_new()

2022-12-07T13:27:22Z

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-440-uwe@kleine-koenig.org

mfd: max77620: Fix refcount leak in max77620_initialise_fps

2022-07-19T09:54:39Z

of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

mfd: max77620: Use single-byte writes on MAX77620

2020-05-26T09:51:21Z

The MAX77620 doesn't support bulk writes, so make sure the regmap code breaks bulk writes into multiple single-byte writes. Note that this is mostly cosmetic because currently only the RTC sub- driver uses bulk writes and the RTC driver ends up using a different regmap on the MAX77620 anyway. However, it seems like a good idea to make this change now in order to avoid running into issues if bulk writes are ever used by other sub-drivers sometime down the road.

mfd: max77620: Do not allocate IRQs upfront

2019-11-11T08:45:02Z

regmap_add_irq_chip() will try to allocate all of the IRQ descriptors upfront if passed a non-zero irq_base parameter. However, the intention is to allocate IRQ descriptors on an as-needed basis if possible. Pass 0 instead of -1 to fix that use-case. Signed-off-by: Thierry Reding Signed-off-by: Lee Jones

mfd: max77620: Add of_node_put() before return

2019-07-25T13:21:38Z

Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta Signed-off-by: Lee Jones
