siox: bus-gpio: Remove the use of dev_err_probe()

2025-09-06T13:59:59Z

The dev_err_probe() doesn't do anything when error is '-ENOMEM'. Therefore, remove the useless call to dev_err_probe(), and just return the value instead.

siox: bus-gpio: Simplify using devm_siox_* functions

2024-03-08T21:01:10Z

With the devm variant of siox_master_allocate() and siox_master_register() the remove callback can be dropped. This also simplifies the error paths in the probe function.

siox: Don't pass the reference on a master in siox_master_register()

2024-03-08T21:01:09Z

While it's technically fine to pass the ownership of the reference on a struct siox_master from the caller of siox_master_register() to the framework this is hard to use. Instead let the framework take its own reference (that is freed in siox_master_unregister()) and drop the bus driver's reference in its remove callback.

headers: separate linux/mod_devicetable.h from linux/platform_device.h

At over 4000 #includes, is the 9th most #included header file in the Linux kernel. It does not need , so drop that header and explicitly add to source files that need it. 4146 #include After this patch, there are 225 files that use , for a reduction of around 3900 times that does not have to be read & parsed. 225 #include This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.
