[PATCH v5] hwmon/pmbus: use simple i2c probe function
From: Stephen Kitt
Date: Sat Aug 08 2020 - 17:00:21 EST
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.
Signed-off-by: Stephen Kitt <steve@xxxxxxx>
---
Changes since v1:
- i2c_device_id declarations are left unchanged;
- all drivers are converted, using client info or i2c_match_id().
Changes since v2:
- updated the documentation;
- fixed unbalanced braces around the modified else in ibm-cffps.c.
Changes since v3:
- fix ltc2978 to avoid assuming names and driver_data are bijective,
and that driver_data are indexes into ltc2978_id.
Changes since v4:
- explicitly case id->driver_data to int in a printk call.
