Qianfeng Rong 2a7265a77e 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().

Fixes: 5691b23489 ("staging:iio:dac: Add AD5421 driver")
