kernel test robot warns:
cast to smaller integer type 'enum ath12k_hw_rev' from 'const void *'

looks like others have fixed this by first casting to (uintptr_t)
a few examples:

tsa->version = (enum tsa_version)(uintptr_t)of_device_get_match_data(&pdev->dev);
model = (enum ep93xx_soc_model)(uintptr_t)device_get_match_data(dev);
priv->cks = (u8)(uintptr_t) of_device_get_match_data(dev);
rt5677->type = (enum rt5677_type)(uintptr_t)device_get_match_data(dev);

not sure if there is a "better" way
