If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai [ Upstream commit 7e37c851374eca2d1f6128de03195c9f7b4baaf2 ] The buck and linear range LDO (VSRAM_*) regulators share one set of ops. This set includes support for get/set mode. However this only makes sense for buck regulators, not LDOs. The callbacks were not checking whether the register offset and/or mask for mode setting was valid or not. This ends up making the kernel report "normal" mode operation for the LDOs. Create a new set of ops without the get/set mode callbacks for the linear range LDO regulators.
