[PATCH v2 1/2] hwmon: gpio-fan: drop of_match_ptr for ID table

[PATCH v2 1/2] hwmon: gpio-fan: drop of_match_ptr for ID table

[Krzysztof Kozlowski]

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here).  This
also fixes !CONFIG_OF error:

  drivers/hwmon/gpio-fan.c:484:34: error: ‘of_gpio_fan_match’ defined but not used [-Werror=unused-const-variable=]

[PATCH v2 2/2] hwmon: tmp512: drop of_match_ptr for ID table

[Krzysztof Kozlowski]

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:

  drivers/hwmon/tmp513.c:610:34: error: ‘tmp51x_of_match’ defined but not used [-Werror=unused-const-variable=]

Applied, though I added a note describing that the above build error can
only be seen if the OF -> GPIO_OF dependency is broken.

Thanks,
