Subject[PATCH 4.19 189/234] ASoC: wm_adsp: Fix event generation for wm_adsp_fw_put()
Date
From: Mark Brown <broonie@kernel.org>

[ Upstream commit 2abdf9f80019e8244d3806ed0e1c9f725e50b452 ]

Currently wm_adsp_fw_put() returns 0 rather than 1 when updating the value
of the control, meaning that no event is generated to userspace. Fix this
by setting the default return value to 1, the code already exits early with
a return value of 0 if the value is unchanged.
