2024-07-04mfd: tps65912: Use devm helper functions to simplify probeAndrew Davis1-8/+0
This simplifies probe and also allows us to remove the remove callbacks from the core and interface drivers. Do that here. Signed-off-by: Andrew Davis <afd@ti.com> Link: https://lore.kernel.org/r/20240613175430.57698-1-afd@ti.com Signed-off-by: Lee Jones <lee@kernel.org>
2024-07-04mfd: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König1-1/+1
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.

2023-06-15mfd: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
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.

2022-12-07mfd: tps65912-i2c: Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221118224540.619276-475-uwe@kleine-koenig.org
2022-08-16i2c: Make remove callback return voidUwe Kleine-König1-3/+1
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.

2021-11-05mfd: tps65912: Make tps65912_device_exit() return voidUwe Kleine-König1-1/+3
Up to now tps65912_device_exit() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

2020-08-13mfd: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2017-02-13mfd: tps65912: Export OF device ID table as module aliasesJavier Martinez Canillas1-0/+1
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.
