From: Mark Brown <broonie@kernel.org>
commit b4f5c6b2e52b27462c0599e64e96e53b58438de1 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.
