| 8 | commit d66777caa57ffade6061782f3a4d4056f0b0c1ac upstream. | |
| 9 | ||
| 10 | pwm4 is enabled if bit 2 of GPIO control register 4 is disabled, | |
| 11 | not when it is enabled. Since the check is for the skip condition, | |
| 12 | it is reversed. This applies to both IT8620 and IT8628. | |
| 13 | ||
| 14 | Fixes: 36c4d98a7883d ("hwmon: (it87) Add support for all pwm channels ...") | |
