Exposure of driver bind/unbind to userspace via sysfs may
lead to unexpected behavior.
Hide bind and unbind by driver attribute.

TX hold callback returns without making a callback
to external codec if the ADC with number one is called.
Add the condition for the missing ADC to make the callback
for ADC1.

Invalid memory access happens in wcd937x_suspend if
component bind for slave fails. This is because
as part of component_unbind devres_release_group is called
which removes every node from list and frees corresponding memory.
This results in invalid memory access for wcd937x in wcd937x_suspend.
Do kfree and set drvdata to NULL if component_bind fails
to resolve the issue.

Replace all kernel make export <all variables> instances with
export of specific variables. Depending on existing build
environment, exporting all as environment variables and
interaction with existing environment variable expansions
can lead to undefined behavior.
TODO: This change is restricted to kona flow to narrow impact.
All remaining export <all variables> need to be evaluated and
fixed similarly via subsequent changes.

When SSR happens, use dev_up flag in codec
to bail out from clock enablement routine.
During interrupt processing if clock enable fails during
SSR, exit isr routine without disabling clock.

Get Logical Address failure comes after SSR during rigorous testing.
This calls removal of swr master device attached. Once removal occurs
further headset insertion/removal does not get detected. Do not remove
swr master device attached to fix the issue.

On some platforms, WCD SPI bus can be shared with other processors
(ex: sensor processor). In such cases, there is need for software
to arbitrate the bus control. Add functionality to perform SPI bus
arbitration.
