[PATCH v1 2/8] media: cec: core: add missing mutex_destroy to error path and remove

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Add missing mutex_destroy() call to error path and remove to properly
clean up the mutex initialized during adapter allocation. Ensure proper
resource cleanup and follows kernel practices.

Found by code review.
