hwmon: (tmp421) Correct the misspelling of the tmp442 compatible attribute in OF device ID table

2019-02-27T09:09:50+00:00

[ Upstream commit f422449b58548a41e98fc97b259a283718e527db ] Correct a typo in OF device ID table The last one should be 'ti,tmp442' Signed-off-by: Cheng-Min Ao Signed-off-by: Yu-Hsiang Chen Signed-off-by: Guenter Roeck Signed-off-by: Sasha Levin

hwmon: (nct6775) Enable IO mapping for NCT6797D and NCT6798D

2019-02-27T09:09:45+00:00

[ Upstream commit 9de15c95a63f527c8f7a968cd95e6ec71fc6891d ] Similar to other recent chips from Nuvoton, IO mapping may be disabled by default. Enable it when instantiating the driver and after resume.

hwmon: (nct6775) Fix chip ID for NCT6798D

2019-02-27T09:09:45+00:00

[ Upstream commit 264142bc70ec039e26d8f3b46a717e8037f59ca0 ] The chip ID is 0xd42[8-f], not 0xd45[8-f]. Fixes: 0599682b826f ("hwmon: (nct6775) Add support for NCT6798D") Reported-by: Michael Cook Cc: Michael Cook Signed-off-by: Guenter Roeck Signed-off-by: Sasha Levin

hwmon: (lm80) Fix missing unlock on error in set_fan_div()

2019-02-23T08:08:07+00:00

[ Upstream commit 07bd14ccc3049f9c0147a91a4227a571f981601a ] Add the missing unlock before return from function set_fan_div() in the error handling case.

hwmon: (lm80) fix a missing check of bus read in lm80 probe

2019-02-12T19:02:28+00:00

[ Upstream commit 9aa3aa15f4c2f74f47afd6c5db4b420fadf3f315 ] In lm80_probe(), if lm80_read_value() fails, it returns a negative error number which is stored to data->fan[f_min] and will be further used. We should avoid using the data if the read fails. The fix checks if lm80_read_value() fails, and if so, returns with the error number.

[ Upstream commit c9c63915519b1def7043b184680f33c24cd49d7b ] If lm80_read_value() fails, it returns a negative number instead of the correct read data. Therefore, we should avoid using the data if it fails. The fix checks if lm80_read_value() fails, and if so, returns with the error number.

hwmon: (w83795) temp4_type has writable permission

2018-11-18T22:34:56+00:00

Both datasheet and comments of store_temp_mode() tell us that temp1~4_type is writable, so fix it. Signed-off-by: Yao Wang Signed-off-by: Huacai Chen Fixes: 39deb6993e7c (" hwmon: (w83795) Simplify temperature sensor type handling") Signed-off-by: Guenter Roeck

hwmon: (mlxreg-fan) Fix macros for tacho fault reading

2018-11-16T16:10:23+00:00

Fix macros for tacometer fault reading. This fix is relevant for three Mellanox systems MQMB7, MSN37, MSN34, which are about to be released to the customers. At the moment, none of them is at customers sites. Fixes: 65afb4c8e7e4 ("hwmon: (mlxreg-fan) Add support for Mellanox FAN driver") Signed-off-by: Vadim Pasternak Signed-off-by: Guenter Roeck

hwmon: (ina2xx) Fix current value calculation

2018-11-14T17:11:24+00:00

The current register (04h) has a sign bit at MSB. The comments for this calculation also mention that it's a signed register. However, the regval is unsigned type so result of calculation turns out to be an incorrect value when current is negative. This patch simply fixes this by adding a casting to s16.

hwmon: (raspberrypi) Fix initial notify

2018-11-13T17:33:32+00:00

In case an under-voltage happens before probing the driver wont write the critical warning into the kernel log. So don't init of last_throttled during probe and fix this issue.
