Qianfeng RongandGreg Kroah-Hartman 3f88f4e8f1 iio: dac: ad5421: use int type to store negative error codes ...

commit 3379c90032 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().
