spmi: add a helper to look up an SPMI device from a device node

2022-06-18T12:48:19+00:00

The helper function spmi_device_from_of() takes a device node and
returns the SPMI device associated with it.
This is like of_find_device_by_node but for SPMI devices.

bus: Make remove callback return void

2021-07-21T09:53:42+00:00

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

spmi: fix some coding style issues at the spmi core

2020-12-10T09:45:36+00:00

While preparing to port the HiSilicon 6421v600 SPMI driver,
I noticed some coding style issues at the SPMI core.

Address them.

spmi: get rid of a warning when built with W=1

2020-12-10T09:45:35+00:00

The SPMI core complaing with this warning when built with W=1:

	drivers/spmi/spmi.c: In function ‘spmi_controller_remove’:
	drivers/spmi/spmi.c:548:6: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable]
	  548 |  int dummy;
	      |      ^~~~~

As the dummy var isn't needed, remove it.

The variable p is a data structure which is used by the driver core
internally and it is not expected that busses will be directly accessing
these driver core internal only data.

spmi: Auto-populate driver.owner in spmi_driver_register()

2015-09-21T02:32:02+00:00

Populate the owner field of the spmi driver when
spmi_driver_register() is called in a similar fashion to how
other *_driver_register() functions do it. This saves driver
writers from having to do this themselves.
