Now that the SPDX tag is in all greybus files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/greybus files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

gb_audio_manager_module_descriptor's intf_id field maintains the
information about the interface on which module is connected hence
having an extra slot field is redundant.
Thus remove the slot field and its associated code.

gb_audio_manager_module_descriptor's cport field is actually used to
manage and pass interface id to user space.
Thus rename gb_audio_manager_module_descriptor's 'cport' field and
few other things to avoid confusion.

Currently, single field is used to report device type say SPK,
MIC, HS, HP, etc. However above HAL expects separate fields for
input & ouput device types.

This is a simple module that keeps a list of connected GB audio
modules.
Whenever a device is attached, an appropriate uevent is sent to
userspace:
UDEV [4941.803215] add /kernel/gb_audio_manager/0 (gb_audio_manager)
ACTION=add
CPORT=99
DEVICES=0x10
DEVPATH=/kernel/gb_audio_manager/0
NAME=naim
PID=64
SEQNUM=1828
SLOT=2
SUBSYSTEM=gb_audio_manager
USEC_INITIALIZED=802416
VID=128
And whenever removed:
UDEV [4941.836588] remove /kernel/gb_audio_manager/0 (gb_audio_manager)
ACTION=remove
DEVPATH=/kernel/gb_audio_manager/0
SEQNUM=1833
SUBSYSTEM=gb_audio_manager
USEC_INITIALIZED=835681
The API consists of functions for adding, removing and inspecting
added device module descriptions (struct gb_audio_module):
int gb_audio_manager_add(struct gb_audio_module_descriptor *desc);
int gb_audio_manager_remove(int id);
int gb_audio_manager_remove_all(void);
struct gb_audio_module* gb_audio_manager_get_module(int id);
void gb_audio_manager_put_module(struct gb_audio_module *module);
int gb_audio_manager_dump_module(int id);
void gb_audio_manager_dump_all(void);
Devices can be inspected through sysfs in /sys/kernel/gb_audio_manager/{id}/*
If GB_AUDIO_MANAGER_SYSFS is exported as 'true', managing devices can be done
via the SYSFS as well. For instance:
echo name=naim slot=2 vid=128 pid=64 cport=99 devices=0x10 > /sys/kernel/gb_audio_manager/add
echo all > /sys/kernel/gb_audio_manager/dump
echo 2 > /sys/kernel/gb_audio_manager/dump
echo 2 > /sys/kernel/gb_audio_manager/remove
