If anyone has any objections, please let me know. ------------------ From: William Breathitt Gray commit d37623132a6347b4ab9e2179eb3f2fa77863c364 upstream. Attempting to load the pci-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.
