max149x6_reg_read()

int max149x6_reg_read	(	struct max149x6_desc *	desc,
		uint32_t	addr,
		uint32_t *	val
	)

Read the value of a device register.

Read the value of a device register

Parameters

desc	- device descriptor for the MAX149X6
addr	- address of the register
val	- value of the register

Returns

0 in case of success, negative error code otherwise
