Subject: [Intel-wired-lan] [PATCH v2 12/25] docs: kdoc_parser: ignore
context analysis and lock attributes

From: Randy Dunlap <redacted>

Drop all context analysis and lock (tracking) attributes to avoid
kernel-doc warnings.

Invalid C declaration: Expected end of definition. [error at 96]
  int kref_put_mutex (struct kref *kref, void (*release)(struct kref
*kref), struct mutex *mutex) __cond_acquires(true# mutex)

The regex is suggested by Mauro; mine was too greedy. Thanks.
Updated context analysis and lock macros list provided by PeterZ.
Thanks.
