hwmon: (sht15) Fix memory leak if regulator_enable() fails

2013-03-20T20:05:00Z

Commit 3e78080f8148 ('hwmon: (sht15) Check return value of regulator_enable()') depends on the use of devm_kmalloc() for automatic resource cleanup in the failure cases, which was introduced in 3.7. In older stable branches, explicit cleanup is needed. Signed-off-by: Ben Hutchings Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

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

hwmon: (pmbus/ltc2978) Fix temperature reporting

2013-03-20T20:04:59Z

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

2013-03-14T18:29:49Z

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

2013-03-14T18:29:49Z

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()

2013-03-14T18:29:49Z

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: (lm73} Detect and report i2c bus errors

2013-01-17T16:50:52Z

commit 0602934f302e016e2ea5dc6951681bfac77455ef upstream. 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 Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

x86,AMD: Power driver support for AMD's family 16h processors

commit 22e32f4f57778ebc6e17812fa3008361c05d64f9 upstream. Add family 16h PCI ID to AMD's power driver to allow it report power consumption on these processors. Signed-off-by: Boris Ostrovsky Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

hwmon: (w83627ehf) Force initial bank selection

2012-11-17T21:16:12Z

commit 3300fb4f88688029fff8dfb9ec0734f6e4cba3e7 upstream. Don't assume bank 0 is selected at device probe time. This may not be the case. Force bank selection at first register access to guarantee that we read the right registers upon driver loading.

hwmon: (ad7314) Add 'name' sysfs attribute

2012-10-02T17:30:06Z

commit 3ceefe4319636d89d4bdf40dca9471970f942e4f upstream. The 'name' sysfs attribute is mandatory for hwmon devices, but was missing in this driver. Cc: Jonathan Cameron Signed-off-by: Guenter Roeck Acked-by: Jean Delvare Acked-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman
