If anyone has any objections, please let me know. ------------------ From: William Breathitt Gray commit c4d35e635f3a65aec291a6045cae8c99cede5bba upstream. Attempting to load the 104-idio-16 module fails during regmap initialization with a return error -EINVAL. This is a result of the regmap cache failing initialization. Set the idio_16_regmap_config max_register member to fix this failure.
