Remove the use of struct_mutex from intel_guc_log.c and replace it with a dedicated lock, guc_lock, defined within the intel_guc_log struct. The struct_mutex was previously used to protect concurrent access and modification of intel_guc_log->level in intel_guc_log_set_level(). However, it was suggested that the lock should reside within the intel_guc_log struct itself. Initialize the new guc_lock in intel_guc_log_init_early(), alongside the existing relay.lock. The lock is initialized using drmm_mutex_init(), which also ensures it is properly destroyed when the driver is unloaded.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
