Hello Andy Thanks for pointing to my patch series > > Thanks Andy for pointing to George's patch series. > > I can drop the mutex_init() part and add just the debugfs part. Hello Marek I started to propose devm_mutex_init in December 2023. We tried to put it in devm-helpers.h firstly then we came to conclusion that linux/mutex.h would be a better place for it. Now I'm waiting for this series [1] to be merged because my patch depends on it. I'll let you know when I have an update.
