commit 33a7ab91d509fa33b4bcd3ce0038cc80298050da upstream. The W83L786NG stores the fan speed on 4 bits while the sysfs interface uses a 0-255 range. Thus the driver should scale the user input down to map it to the device range, and scale up the value read from the device before presenting it to the user. The reserved register nibble should be left unchanged.

commit efabcc2123f0ed47870033b8d6fc73b50d76d635 upstream. Some I2C bus drivers do not allow zero-length data transfers which are required to start a measurement with the HIH6130/1 sensor. Nevertheless, we can overcome this limitation by writing a zero dummy byte. This byte is ignored by the sensor and was verified to be working with the OMAP I2C bus driver in a BeagleBone board.

2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.
