mfd: Explicitly include correct DT includes

2023-08-18T20:48:03+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

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: da9052-i2c: Remove MODULE_LICENSE in non-modules

2023-04-26T10:40:32+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

mfd: da9052-i2c: Convert to i2c's .probe_new()

2022-12-07T13:27:21+00:00

.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

mfd: da9052: Simplify function return logic

2015-10-30T17:19:46+00:00

The invoked functions already return zero on success or a negative
errno code so there is no need to open code the logic in the caller.
