2021-10-12hwmon: cleanup non-bool "valid" data fieldsPaul Fertser
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.

2021-04-20hwmon: replace snprintf in show functions with sysfs_emitGuenter Roeck
coccicheck complains about the use of snprintf() in sysfs show functions. drivers/hwmon/ina3221.c:701:8-16: WARNING: use scnprintf or sprintf This results in a large number of patch submissions. Fix it all in one go using the following coccinelle rules. Use sysfs_emit instead of scnprintf or sprintf since that makes more sense. @depends on patch@ identifier show, dev, attr, buf; @@ ssize_t show(struct device *dev, struct device_attribute *attr, char *buf) { <... return - snprintf(buf, \( PAGE_SIZE \| PAGE_SIZE - 1 \), + sysfs_emit(buf, ...); ...> } @depends on patch@ identifier show, dev, attr, buf, rc; @@ ssize_t show(struct device *dev, struct device_attribute *attr, char *buf) { <... rc = - snprintf(buf, \( PAGE_SIZE \| PAGE_SIZE - 1 \), + sysfs_emit(buf, ...); ...> } While at it, remove unnecessary braces and as well as unnecessary else after return statements to address checkpatch warnings in the resulting patch.

2020-09-23hwmon: use simple i2c probe functionStephen Kitt
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: (max16065) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck
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>
