mfd: sm501: Fix mismatches of request_mem_region
This driver misuses release_resource + kfree to match request_mem_region, which is incorrect. The right way is to use release_mem_region. Replace the mismatched calls with the right ones to fix it. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
