2020-09-23hwmon: use simple i2c probe functionStephen Kitt1-4/+3
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.

2017-01-10hwmon: (tmp401) use smb word operations instead of 2 smb byte operationsJeroen De Wachter1-35/+14
tmp401 separately read/wrote high and low bytes of temperature values while the hardware supports reading/writing those values in one operation. Driver has been modified to use word operations where possible. Tested with a tmp432 sensor on a mips64 platform.

2017-01-02hwmon: (tmp401) use permission-specific DEVICE_ATTR variantsJulia Lawall1-6/+5
Use DEVICE_ATTR_RW for read/write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.

The return value of i2c_smbus_read_byte_data() is checked in tmp401_init_client(), but only a warning is printed and the device is registered anyway. This leads to devices being registered even if they cannot be physically detected. Bail out from probe in case of write errors and notify the user.
