Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script. Link: https://lore.kernel.org/r/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/Signed-off-by:

The mx25_tsadc_remove() function assumes all non-zero returns are success but the platform_get_irq() function returns negative on error and positive non-zero values on success. It never returns zero, but if it did then treat that as a success. Fixes: 18f77393 ("mfd: fsl-imx25: Clean up irq settings during removal") Signed-off-by:

There are two bindings for Qualcomm SPMI PMIC Thermal Monitoring ADC: one for ADC HC and one for ADC TM5 and TM7. PM8998 uses the former one, so fix matching of child schema: qcom/msm8998-asus-novago-tp370ql.dtb: pmic@0: adc-tm@3400:compatible:0: 'qcom,spmi-adc-tm-hc' is not one of ['qcom,spmi-adc-tm5', 'qcom,spmi-adc-tm5-gen2', 'qcom,adc-tm7'] Fixes: 3f5117be ("dt-bindings: mfd: convert to yaml Qualcomm SPMI PMIC") Signed-off-by:

The syscon bindings require a device specific compatible, beside the "syscon". However schema counts "simple-mfd" as such, which allows simple-mfd+syscon to sneak in. Adjust the match to be sure simple-mfd also comes with a device specific compatible. Signed-off-by:

When we consider MFD which implements hotplug (e.g. USB hotplug driver based on product and vendor IDs) functionality it turns out that its sub-devices are correctly matched with corresponding device tree nodes only at the first time. When physical device reboots or is replugged (and MFD driver is disconnected and probed back again) all sub-devices fails in mfd_add_device() with error 'Failed to locate of_node'. The reason of that behavior is that when any MFD sub-device is created for the first time (and matched with device tree node) it is added to the mfd_of_node_list. It looks like this list is never cleaned even if devices added there are intentionally removed from the system. So when MFD device is replugged and all sub-devices are matched with their device tree nodes again they fail as matched nodes already exist in mfd_of_node_list. In other words current implementation does not support MFD with hotplug feature. This commit extends MFD core for hotplugging support by removing appropriate OF node entry from mfd_of_node_list when corresponding device is removed from the system. Thanks to that when device is added once again it can be matched with its device tree node successfully. Signed-off-by:

In lp8788_irq_init(), if an error occurs after a successful irq_domain_add_linear() call, it must be undone by a corresponding irq_domain_remove() call. irq_domain_remove() should also be called in lp8788_irq_exit() for the same reason. Fixes: eea6b7cc ("mfd: Add lp8788 mfd driver") Signed-off-by:

If devm_of_platform_populate() fails, some resources need to be released.

To reflect the point that this driver is only for one type of the PMICs, replace intel_soc_pmic with crystal_cove (avoid using crc for possible namespace collisions with CRC library APIs). Note, also rename the driver name since we don't expect any user that enumerates by it, only ACPI known so far. Signed-off-by:

Use sub-function of_compatible during probe, instead of using the node name. The code should not rely on the node names during probe, in addition to that the previously hard-coded node names are not compliant to the latest naming convention (they are not generic and they use underscores), and it was broken by mistake already once [1].

The VSC7512 is a networking chip that contains several peripherals. Many of these peripherals are currently supported by the VSC7513 and VSC7514 chips, but those run on an internal CPU. The VSC7512 lacks this CPU, and must be controlled externally. Utilize the existing drivers by referencing the chip as an MFD. Add support for the two MDIO buses, the internal phys, pinctrl, and serial GPIO. Signed-off-by:
