* hwmon: (ultra45_env) Introduce managed version of kzallocHimangi Saraogi2014-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. Also, the unnecessary label out_free is removed. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (lm80) Normalize all temperature values to 16 bitGuenter Roeck2014-05-21
| | | | | | | Normalize all stored temperature values to 16 bit to simplify temperature calculations. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (lm80) Simplify TEMP_FROM_REGGuenter Roeck2014-05-21
| | | | | | | | | | | | | TEMP_FROM_REG gets 12 bits of temperature data in the upper 12 bit of a signed 16 bit parameter, with the integer part (including sign) in the upper 8 bit and the remainder in bit 4..7. The lower 4 bit of the 16 bit data is always 0. We can use that information to convert the temperature directly into display data (1/1000th of degree C). Note that the stored temperature data is not shifted right as the comment claimed, so remove that misleading comment. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (max1619) Fix critical alarm displayGuenter Roeck2014-05-21
| | | | | | | | | The overtemperature status bit, which is used to display critical alarm status, matches the output of the OVERT signal 1:1. If that signal is active-low, the bit will read 1 if there is no alarm. It is therefore necessary to reverse the bit in this case. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (emc1403) Relax hysteresis limit write checksGuenter Roeck2014-05-21
| | | | | | | | | Writing the hysteresis limit returned -ERANGE if the written hysteresis was too high or too low. Relax error check and adjust the hysteresis value to its valid range. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-onlyGuenter Roeck2014-05-21
| | | | | | | | | | All chips in this chip series only support a single hysteresis value. Having multiple writable hysteresis attributes is therefore confusing, since a single write affects all hysteresis temperatures. Make all but one (temp1_crit_hyst) read-only.
