mfd: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-07-04T16:08:02+00:00

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

While add it, also remove commas after the sentinel entries.

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: wm8350-i2c: Convert to i2c's .probe_new()

2022-12-07T13:27:26+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

mfd: wm8350-i2c: Make it explicitly non-modular

2019-02-01T08:21:13+00:00

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_WM8350_I2C
drivers/mfd/Kconfig:    bool "Wolfson Microelectronics WM8350 with I2C"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

We don't replace module.h with init.h since the file already has that.
But we do delete an unused moduleparam.h

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

mfd: Drop owner assignment from i2c_drivers

2015-08-11T14:08:48+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

mfd: Add regmap cache support for wm8350

2012-07-08T22:16:10+00:00

Use the most simple possible transformation on the existing code so keep
the table sitting around, further patches in this series will delete the
existing cache code - the main purpose of this patch is to ensure that
we always have a cache for bisection.
