hwmon: (tmp401) Drop support for TMP461 TMP461 is almost identical to TMP451, which is already supported by the lm90 driver. At the same time, unlike other sensors from the TMP401 compatible series, it only supports 8-bit temperature read operations, and it supports negative temperatures when configured for its default temperature range, and it supports a temperature offset register. Supporting this chip in the tmp401 driver adds unnecessary complexity. Remove its support from this driver and support the chip with the lm90 driver instead.

The register addresses for other sensors are the same for all chips. It is therefore unnecessary to maintain two different arrays for TMP431 and the other chips.

hwmon: Use named initializers for arrays of i2c_device_data While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify indention and usage of commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

hwmon: (tmp401) fix overflow caused by default conversion rate value The driver computes conversion intervals using the formula: interval = (1 << (7 - rate)) * 125ms where 'rate' is the sensor's conversion rate register value. According to the datasheet, the power-on reset value of this register is 0x8, which could be assigned to the register, after handling i2c general call. Using this default value causes a result greater than the bit width of left operand and an undefined behaviour in the calculation above, since shifting by values larger than the bit width is undefined behaviour as per C language standard. Limit the maximum usable 'rate' value to 7 to prevent undefined behaviour in calculations. Found by Linux Verification Center (linuxtesting.org) with Svace. Note (groeck): This does not matter in practice unless someone overwrites the chip configuration from outside the driver while the driver is loaded. The conversion time register is initialized with a value of 5 (500ms) when the driver is loaded, and the driver never writes a bad value.

hwmon: use simple i2c probe function 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.

hwmon: (tmp401) Drop support for TMP461 TMP461 is almost identical to TMP451, which is already supported by the lm90 driver. At the same time, unlike other sensors from the TMP401 compatible series, it only supports 8-bit temperature read operations, and it supports negative temperatures when configured for its default temperature range, and it supports a temperature offset register. Supporting this chip in the tmp401 driver adds unnecessary complexity. Remove its support from this driver and support the chip with the lm90 driver instead.

hwmon: (tmp401) Remove use of i2c_match_id() The function i2c_match_id() is used to fetch the matching ID from the i2c_device_id table. This is often used to then retrieve the matching driver_data. This can be done in one step with the helper i2c_get_match_data(). This helper has a couple other benefits: * It doesn't need the i2c_device_id passed in so we do not need to have that forward declared, allowing us to remove those or move the i2c_device_id table down to its more natural spot with the other module info. * It also checks for device match data, which allows for OF and ACPI based probing. That means we do not have to manually check those first and can remove those checks.

hwmon: (tmp401) Add support for TI's TMP401 sensor chip This is a new hwmon driver for TI's TMP401 temperature sensor IC. This driver was written on behalf of an embedded systems vendor under the Linux driver project. It has been tested using a TI TMP401 sample attached to a i2c-tiny-usb adapter. Which was provided by Till Harbaum, many thanks to him for this! Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
