hwmon: (lineage-pem) Add missing terminating entry for pem_[input|fan]_attributes

hwmon: (pmbus/ltc2978) Fix temperature reporting

2013-03-20T20:10:55Z

commit 8c958c703ef8804093437959221951eaf0e1e664 upstream. On LTC2978, only READ_TEMPERATURE is supported. It reports the internal junction temperature. This register is unpaged. On LTC3880, READ_TEMPERATURE and READ_TEMPERATURE2 are supported. READ_TEMPERATURE is paged and reports external temperatures. READ_TEMPERATURE2 is unpaged and reports the internal junction temperature. Signed-off-by: Guenter Roeck Acked-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

hwmon: (pmbus/ltc2978) Use detected chip ID to select supported functionality

2013-03-14T18:26:23Z

commit f366fccd0809f13ba20d64cae3c83f7338c88af7 upstream. We read the chip ID from the chip, use it to determine if the chip ID provided to the driver is correct, and report it if wrong. We should also use the correct chip ID to select supported functionality. Signed-off-by: Guenter Roeck Acked-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

hwmon: (pmbus/ltc2978) Fix peak attribute handling

2013-03-14T18:26:23Z

commit dbd712c2272764a536e29ad6841dba74989a39d9 upstream. Peak attributes were not initialized and cleared correctly. Also, temp2_max is only supported on page 0 and thus does not need to be an array. Signed-off-by: Guenter Roeck Acked-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

hwmon: (sht15) Check return value of regulator_enable()

2013-03-14T18:26:22Z

commit 3e78080f81481aa8340374d5a37ae033c1cf4272 upstream. Not having power is a pretty serious error so check that we are able to enable the supply and error out if we can't. Signed-off-by: Mark Brown Signed-off-by: Guenter Roeck

hwmon: (vexpress) Fix build error seen if CONFIG_OF_DEVICE is not set

2013-01-10T05:47:22Z

Fix: vexpress.c: In function ‘vexpress_hwmon_name_show’: vexpress.c:34:2: error: implicit declaration of function ‘of_get_property’ [-Werror=implicit-function-declaration] vexpress.c:34:27: warning: initialization makes pointer from integer without a cast [enabled by default] vexpress.c: In function ‘vexpress_hwmon_label_show’: vexpress.c:43:22: warning: initialization makes pointer from integer without a cast [enabled by default] Seen if CONFIG_OF_DEVICE is not defined. of_get_property is declared in of.h which is only included by of_device.h if CONFIG_OF_DEVICE is defined. of.h needs to be included directly.

Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman

hwmon: (emc6w201) Fix DIV_ROUND_CLOSEST problem with unsigned divisors

2012-12-22T10:16:40Z

Result of DIV_ROUND_CLOSEST is undefined for negative dividends if the divisor variable type is unsigned. Fix by declaring divisor as signed variable. Signed-off-by: Guenter Roeck Acked-by: Jean Delvare

hwmon: (lm73} Detect and report i2c bus errors

2012-12-22T01:59:30Z

If an LM73 device does not exist on an I2C bus, attempts to communicate with the device result in an error code returned from the i2c read/write functions. The current lm73 driver casts that return value from a s32 type to a s16 type, then converts it to a temperature in celsius. Because negative temperatures are valid, it is difficult to distinguish between an error code printed to the response buffer and a negative temperature recorded by the sensor. The solution is to evaluate the return value from the i2c functions before performing any temperature calculations. If the i2c function did not succeed, the error code should be passed back through the virtual file system layer instead of being printed into the response buffer. Before: $ cat /sys/class/hwmon/hwmon0/device/temp1_input -46 After: $ cat /sys/class/hwmon/hwmon0/device/temp1_input cat: read error: No such device or address Signed-off-by: Chris Verges Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck

hwmon-vid: Add support for AMD family 11h to 15h processors

2012-12-19T21:17:02Z

Since family 11h processors, AMD is exclusively using 7-bit VID codes transmitted using a serial protocol over two pins (clock and data.) Signed-off-by: Jean Delvare Tested-by: David Hubbard Reviewed-by: Guenter Roeck
