If anyone has any objections, please let me know. ------------------ From: Qianfeng Rong commit 3379c900320954d768ed9903691fb2520926bbe3 upstream. Change the 'ret' variable in ad5421_update_ctrl() from unsigned int to int, as it needs to store either negative error codes or zero returned by ad5421_write_unlocked().
