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.

2021-04-20hwmon: (pmbus) Introduce PMBUS symbol namespaceGuenter Roeck1-0/+1
Exported pmbus symbols are only supposed to be used from PMBus code. Introduce PMBUS symbol namespace to prevent misuse from other code. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2021-04-20hwmon: replace snprintf in show functions with sysfs_emitGuenter Roeck1-14/+14
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.

2020-12-03hwmon: (pmbus) shrink code and remove pmbus_do_remove()Bartosz Golaszewski1-1/+0
The only action currently performed in pmbus_do_remove() is removing the debugfs hierarchy. We can schedule a devm action at probe time and remove pmbus_do_remove() entirely from all pmbus drivers.

2020-09-23hwmon (pmbus) use simple i2c probe functionStephen Kitt1-4/+3
pmbus_do_probe doesn't use the id information provided in its second argument, so this can be removed, which then allows using the single-parameter i2c probe function ("probe_new") for probes. 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); * configured v. probed comparisons are performed by comparing the configured name to the detected name, instead of the ids; this involves strcmp but is still cheaper than comparing all the device names when scanning the tables; * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. Additionally, the mismatch message in the ltc2978 driver is adjusted so that it no longer assumes that the driver_data is an index into ltc2978_id.

2019-09-03hwmon: pmbus: Add Inspur Power System power supply driverJohn Wang1-0/+228
Add the driver to monitor Inspur Power System power supplies with hwmon over pmbus. This driver adds sysfs attributes for additional power supply data, including vendor, model, part_number, serial number, firmware revision, hardware revision, and psu mode(active/standby).
