hwmon: (tmp401) Drop redundant safety on cache lifetime

2013-05-19T15:19:29+00:00

time_after (as opposed to time_after_equal) already ensures that the cache lifetime is at least as much as requested. There is no point in manually adding another jiffy to that value, and this can confuse the reader into wrong interpretation.

hwmon: fix error return code in abituguru_probe()

2013-05-13T15:07:13+00:00

Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun Cc: stable@vger.kernel.org Signed-off-by: Guenter Roeck

hwmon: (iio_hwmon) Fix null pointer dereference

2013-05-13T13:43:14+00:00

This patch fixes the null pointer dereference in goto error_release_channels path when allocate memory for st fails. Reported-by: Dan Carpenter Signed-off-by: Axel Lin Signed-off-by: Guenter Roeck

hwmon: (nct6775) Do not create non-existing attributes

2013-05-12T05:55:07+00:00

Overtemperature and hysteresis registers only exist for primary temperature registers, not for alternates, so do not assign those registers when initializing alternates. Signed-off-by: Guenter Roeck

hwmon: (lm75) Add support for the Dallas/Maxim DS7505

2013-05-04T12:49:36+00:00

Basically it's the same as the original DS75 but much faster. Signed-off-by: Jean Delvare Acked-by: Guenter Roeck

hwmon: (lm75) Tune resolution and sample time per chip

2013-05-04T12:49:36+00:00

Most LM75-compatible chips can either sample much faster or with a much better resolution than the original LM75 chip. So far the lm75 driver did not let the user take benefit of these improvements. Do it now. I decided to almost always configure the chip to use the best resolution possible, which also means the longest sample time. The only chips for which I didn't are the DS75, DS1775 and STDS75, because they are really too slow in 12-bit mode (1.2 to 1.5 second worst case) so I went for 11-bit mode as a more reasonable tradeoff. This choice is dictated by the fact that the hwmon subsystem is meant for system monitoring, it has never been supposed to be ultra-fast, and as a matter of fact we do cache the sampled values in almost all drivers. If anyone isn't pleased with these default settings, they can always introduce a platform data structure or DT support for the lm75. That being said, it seems nobody ever complained that the driver wouldn't refresh the value faster than every 1.5 second, and the change made it faster for all chips even in 12-bit mode, so I don't expect any complaint.

hwmon: (lm75) Prepare to support per-chip resolution and sample time

2013-05-04T12:49:36+00:00

Prepare the lm75 driver to support per-chip resolution and sample time. For now we only make the code generic enough to support it, but we still use the same, unchanged resolution (9-bit) and sample time (1.5 s) for all chips. Signed-off-by: Jean Delvare Acked-by: Guenter Roeck
