2024-07-14hwmon: Remove obsolete adm1021 and max6642 driversGuenter Roeck1-314/+0
ADM1021, MAX6642, and compatible chips are supported by the lm90 driver. Remove the obsolete stand-alone drivers to reduce maintenance overhead. Reviewed-by: Tzung-Bi Shih <tzungbi@kernel.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2024-05-01hwmon: 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.

2023-06-08hwmon: 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.

2022-09-19hwmon: move from strlcpy with unused retval to strscpyWolfram Sang1-1/+1
Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

2021-10-12hwmon: cleanup non-bool "valid" data fieldsPaul Fertser1-1/+1
We have bool so use it consistently in all the drivers. The following Coccinelle script was used: @@ identifier T; type t = { char, int }; @@ struct T { ... - t valid; + bool valid; ... } @@ identifier v; @@ ( - v->valid = 0 + v->valid = false | - v->valid = 1 + v->valid = true ) followed by sed to fixup the comments: sed '/bool valid;/{s/!=0/true/;s/zero/false/}' Few whitespace changes were fixed manually. All modified drivers were compile-tested.

2020-09-23hwmon: use simple i2c probe functionStephen Kitt1-3/+2
Many hwmon drivers don't use the id information provided by the old i2c probe function, and the remainder can easily be adapted to the new form ("probe_new") by calling i2c_match_id explicitly. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. A few drivers aren't included in this patch because they have a different set of maintainers. They will be covered by other patches.

2019-02-18hwmon: (max6642) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck1-15/+16
Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readability, and to reduce the chance of inconsistencies. Also replace any remaining S_<PERMS> in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
