[PATCH AUTOSEL 4.19 1/6] ASoC: cs42l56: fix DT probe

[Sasha Levin <sashal@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit e18c6da62edc780e4f4f3c9ce07bdacd69505182 ]

While looking through legacy platform data users, I noticed that
the DT probing never uses data from the DT properties, as the
platform_data structure gets overwritten directly after it
is initialized.

There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels or with the default values.

For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.
