* hwmon: (ad7314) Convert to use devm_ functionsGuenter Roeck2012-09-231-10/+6
| | | | | | Convert to use devm_ functions to reduce code size and simplify the code. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (ad7314) Add 'name' sysfs attributeGuenter Roeck2012-09-181-0/+8
| | | | | | | | | | | The 'name' sysfs attribute is mandatory for hwmon devices, but was missing in this driver.

* hwmon: (ad7314) Remove unused defines, and rename OFFSET to SHIFTGuenter Roeck2012-05-201-9/+2
| | | | | | | | | Remove unused defines AD7314_PD, AD7314_TEMP_SIGN, and ADT7301_TEMP_SIGN. Rename AD7314_TEMP_OFFSET to the more appropriate AD7314_TEMP_SHIFT. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Cc: Jonathan Cameron <jic23@cam.ac.uk> Acked-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (ad7314) Fix build warningGuenter Roeck2012-04-221-7/+5
| | | | | | | | | | | | | | | The following build warning is seen in some configurations. drivers/hwmon/ad7314.c: In function 'ad7314_show_temperature': drivers/hwmon/ad7314.c:70: warning: 'data' may be used uninitialized in this function Fix by overloading the return value from ad7314_spi_read with both data and error code (the returned data is really u16 and needs to be converted into a signed value anyway).

* hwmon: (ad7314) Adds missing spi_dev initializationGraeme Smecher2012-04-031-0/+1
| | | | | | | | | | | This driver was recently moved from IIO (where it worked) to hwmon (where it doesn't.) This breakage occured because the hwmon version neglected to correctly initialize a reference to spi_dev in its drvdata. The result is a segfault every time the temperature is queried.

* hwmon: convert drivers/hwmon/* to use module_spi_driver()Axel Lin2012-03-181-11/+1
| | | | | | | | | | | | | This patch converts the drivers in drivers/hwmon/* to use the module_spi_driver() macro which makes the code smaller and a bit simpler.

* hwmon: Remove redundant spi driver bus initializationLars-Peter Clausen2011-11-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_register_driver(), so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Cc: Jean Delvare <khali@linux-fr.org> Cc: Guenter Roeck <guenter.roeck@ericsson.com> Cc: lm-sensors@lm-sensors.org Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
