ASoC: SOF: don't use "/**" for non-kernel-doc comments

Modify these errant comments to use "/*" since they are not kernel-doc
comments.

Warning: ../include/sound/sof/header.h:182 This comment starts with '/**', but isn't a kernel-doc comment.

ALSA/ASoC: include: clarify Copyright information

2024-05-09T18:26:34+00:00

For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

ASoC: SOF: fix 32 signed bit overflow

2022-03-07T13:12:52+00:00

Shifting in a signed 32bit container past the signed bit is technically
undefined behaviour. Fix by using unsigned types. Found via cppcheck.

ASoC: SOF: trace: Add runtime trace filtering mechanism

2020-12-07T14:22:05+00:00

The "filter" debugfs file defines the log levels used by
the firmware and reported by sof-logger.

The file contains the formatted entry list, where each entry
follows the following syntax in plain text:
log_level uuid_id pipe_id comp_id;

This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.

An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.

When the file is modified, an IPC command is sent to FW with new
trace levels for selected components in filter elements list.

ASoC: SOF: IPC: fix implicit type overflow

2020-11-20T16:42:14+00:00

Implicit values may have a length of 15bits (s16) so we need to declare
the proper size so we don't get undefined behaviour. This appears to be
arch and compiler dependent. This commit is to keep the headers aligned
between the firmware and kernel. UBSan discovered this bug in the
firmware.
