This is not -RT only related. An unpatched kernel should have the same
problem. The EXPORT_SYMBOL_GPL(mutex_destroy) is here since commit
408894ee4dd4 ("[PATCH] mutex subsystem, debugging code") / v2.6.16 by
Ingo Molnar.
You could disable CONFIG_DEBUG_MUTEXES or look for alternatives for this
driver.
