hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-01T14:47:49+00:00

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.

hwmon: Switch i2c drivers back to use .probe()

2023-06-08T13:41:17+00:00

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.

hwmon: (ltc2945) Allow setting shunt resistor

2023-02-03T15:30:10+00:00

Add the ability to specify the value of the shunt resistor in the
device tree instead of assuming it is 1 milliOhm. The value in the
device tree has the name shunt-resistor-micro-ohms and the
default value is 1000 micro-ohms in order to preserve the
current behavior.

hwmon: (ltc2945) Handle error case in ltc2945_value_store

2023-02-03T15:30:10+00:00

ltc2945_val_to_reg errors were not being handled
which would have resulted in register being set to
0 (clamped) instead of being left alone.

hwmon: replace snprintf in show functions with sysfs_emit

2021-04-20T13:50:14+00:00

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.

hwmon: use simple i2c probe function

2020-09-23T16:42:39+00:00

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.
