Merge tag 'asoc-fix-v5.18-rc3' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v5.18

A collection of fixes that came in since the merge window, plus one new
device ID for an x86 laptop.  Nothing that really stands out with
particularly big impact outside of the affected device.

+  the messages.  Leading console timestamps will be stripped.
+
+  Various unittests may trigger kernel messages from outside the
+  unittest code.  The unittest annotates that it expects the message
+  to occur with an 'EXPECT \\ : text' (begin) before triggering the
+  message, and an 'EXPECT / : text' (end) after triggering the message.
+
+  If an expected message does not occur, that will be reported.
+
+  For each expected message, the 'EXPECT \\ : text' (begin) and
+  'EXPECT / : text' (end), 'text' will contain the message text.
+
+  If 'EXPECT \\' (begin) and 'EXPECT /' (end) lines do not contain
+  matching 'text', that will be reported.
+
+  If EXPECT lines are nested, 'EXPECT /' (end) lines must be in the
+  reverse order of the corresponding 'EXPECT \\' (begin) lines.
+
+  'EXPECT \\ : text' (begin) and 'EXPECT / : text' (end) lines can
+  contain special patterns in 'text':
+
+     <<int>> matches: [+-]*[0-9]+
+     <<hex>> matches: (0x)*[0-9a-f]+
+
+  'EXPECT \\' (begin) and 'EXPECT /' (end) lines are suppressed.
+
+  A prefix is added to every line of output:
+
+    'ok ' Line matches an enclosing EXPECT begin/end pair
+
+    '** ' Line reports $script_name warning or error
+
+    '-> ' Line reports start or end of the unittests
+

+
+  Issues detected in CONSOLE_LOG are reported to STDOUT, not to STDERR.

+=head1 DESCRIPTION
 
 Read C language source or header FILEs, extract embedded documentation comments,
 and print formatted documentation to standard output.
 
-The documentation comments are identified by "/**" opening comment mark. See
-Documentation/doc-guide/kernel-doc.rst for the documentation comment syntax.
-
-Output format selection (mutually exclusive):
-  -man			Output troff manual page format. This is the default.
-  -rst			Output reStructuredText format.
-  -none			Do not output documentation, only warnings.
-
-Output format selection modifier (affects only ReST output):
-
-  -sphinx-version	Use the ReST C domain dialect compatible with an
-			specific Sphinx Version.
-			If not specified, kernel-doc will auto-detect using
-			the sphinx-build version found on PATH.
-
-Output selection (mutually exclusive):
-  -export		Only output documentation for symbols that have been
-			exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
-                        in any input FILE or -export-file FILE.
-  -internal		Only output documentation for symbols that have NOT been
-			exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
-                        in any input FILE or -export-file FILE.
-  -function NAME	Only output documentation for the given function(s)
-			or DOC: section title(s). All other functions and DOC:
-			sections are ignored. May be specified multiple times.
-  -nosymbol NAME	Exclude the specified symbols from the output
-		        documentation. May be specified multiple times.
-
-Output selection modifiers:
-  -no-doc-sections	Do not output DOC: sections.
-  -enable-lineno        Enable output of #define LINENO lines. Only works with
-                        reStructuredText format.
-  -export-file FILE     Specify an additional FILE in which to look for
-                        EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with
-                        -export or -internal. May be specified multiple times.
-
-Other parameters:
-  -v			Verbose output, more warnings and other information.
-  -h			Print this help.
-  -Werror		Treat warnings as errors.
-
-EOF
-    print $message;
-    exit 1;
-}
+The documentation comments are identified by the "/**" opening comment mark.
 
-#
-# format of comments.
-# In the following table, (...)? signifies optional structure.
-#                         (...)* signifies 0 or more structure elements
-# /**
-#  * function_name(:)? (- short description)?
-# (* @parameterx: (description of parameter x)?)*
-# (* a blank line)?
-#  * (Description:)? (Description of function)?
-#  * (section header: (section description)? )*
-#  (*)?*/
-#
-# So .. the trivial example would be:
-#
-# /**
-#  * my_function
-#  */
-#
-# If the Description: header tag is omitted, then there must be a blank line
-# after the last parameter specification.
-# e.g.
-# /**
-#  * my_function - does my stuff
-#  * @my_arg: its mine damnit
-#  *
-#  * Does my stuff explained.
-#  */
-#
-#  or, could also use:
-# /**
-#  * my_function - does my stuff
-#  * @my_arg: its mine damnit
-#  * Description: Does my stuff explained.
-#  */
-# etc.
-#
-# Besides functions you can also write documentation for structs, unions,
-# enums and typedefs. Instead of the function name you must write the name
-# of the declaration;  the struct/union/enum/typedef must always precede
-# the name. Nesting of declarations is not supported.
-# Use the argument mechanism to document members or constants.
-# e.g.
-# /**
-#  * struct my_struct - short description
-#  * @a: first member
-#  * @b: second member
-#  *
-#  * Longer description
-#  */
-# struct my_struct {
-#     int a;
-#     int b;
-# /* private: */
-#     int c;
-# };
-#
-# All descriptions can be multiline, except the short function description.
-#
-# For really longs structs, you can also describe arguments inside the
-# body of the struct.
-# eg.
-# /**
-#  * struct my_struct - short description
-#  * @a: first member
-#  * @b: second member
-#  *
-#  * Longer description
-#  */
-# struct my_struct {
-#     int a;
-#     int b;
-#     /**
-#      * @c: This is longer description of C
-#      *
-#      * You can use paragraphs to describe arguments
-#      * using this method.
-#      */
-#     int c;
-# };
-#
-# This should be use only for struct/enum members.
-#
-# You can also add additional sections. When documenting kernel functions you
-# should document the "Context:" of the function, e.g. whether the functions
-# can be called form interrupts. Unlike other sections you can end it with an
-# empty line.
-# A non-void function should have a "Return:" section describing the return
-# value(s).
-# Example-sections should contain the string EXAMPLE so that they are marked
-# appropriately in DocBook.
-#
-# Example:
-# /**
-#  * user_function - function that can only be called in user context
-#  * @a: some argument
-#  * Context: !in_interrupt()
-#  *
-#  * Some description
-#  * Example:
-#  *    user_function(22);
-#  */
-# ...
-#
-#
-# All descriptive text is further processed, scanning for the following special
-# patterns, which are highlighted appropriately.
-#
-# 'funcname()' - function
-# '$ENVVAR' - environmental variable
-# '&struct_name' - name of a structure (up to two words including 'struct')
-# '&struct_name.member' - name of a structure member
-# '@parameter' - name of a parameter
-# '%CONST' - name of a constant.
-# '``LITERAL``' - literal string without any spaces on it.
