* hwmon: move from strlcpy with unused retval to strscpyWolfram Sang2022-09-191-1/+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.

* hwmon: cleanup non-bool "valid" data fieldsPaul Fertser2021-10-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: use simple i2c probe functionStephen Kitt2020-09-231-4/+5
| | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: (thmc50) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck2019-04-161-42/+41
| | | | | | | | | | | | | | | | Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, 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/. 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>
