commit b4f5c6b2e5 upstream.
The WM8958 DSP controls all return 0 on successful write, not a boolean
value indicating if the write changed the value of the control. Fix this
by returning 1 after a change, there is already a check at the start of
each put() that skips the function in the case that there is no change.
