[PATCH v1 1/4] drm/tiny/repaper: Make driver OF-independent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is one OF call in the driver that limits its area of use.
Replace it to generic device_get_match_data() and get rid of OF dependency.

While here, cast SPI driver data to certain enumerator type.
