When the CS35L41 loads its firmware, it has a number of controls to
affect its behaviour. Currently, these controls are exposed as ALSA
Controls.
These controls were never intended to be exposed to users but the
firmware doesn't mark them hidden, so make the driver ignore them.
Any changes in the coefficients handled by these controls needs to
be matched to the individual system by SSID, which is already handled
using the tuning file, when firmware is loaded, so UCM should not be
setting these controls anyway.

A number of laptops have gone to market with old firmware versions that
export controls that have since been hidden, but we can't just install a
newer firmware because the firmware for each product is customized and
qualified by the OEM. The issue is that alsactl save and restore has no
idea what controls are good to persist which can lead to
misconfiguration.
There is no reason that the UCM or user should need to interact with any
of the ALSA controls for the firmware coefficients so they can be
removed entirely, this also simplifies the driver.

by 1. Basically a simple ping-pong command.

If this flag is set, then the reply is expected to consist of
the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as
used in bytes 1-4 of the message), followed by the struct cec_msg reply
field.
Note that this assumes that the byte after the Vendor ID is a
vendor-specific opcode.
This flag makes it easier to wait for replies to vendor commands,
using the same CEC framework support for waiting for regular replies.
Support for this flag is indicated by setting the new
CEC_CAP_REPLY_VENDOR_ID capability.

In the probe, if an error occurs after the ti_iodelay_pinconf_init_dev()
call, it is likely that ti_iodelay_pinconf_deinit_dev() should be called,
as already done in the remove function.
Also in ti_iodelay_pinconf_init_dev(), if an error occurs after the first
regmap_update_bits() call, it is also likely that the deinit() function
should be called.
The easier way to fix it is to add a devm_add_action_or_reset() at the
rigtht place to have ti_iodelay_pinconf_deinit_dev() called when needed.
Doing so, the .remove() function can be removed, and the associated
platform_set_drvdata() call in the probe as well.
