[greybus-dev] Re: [PATCH] staging: greybus: Use guard(mutex) in receive_data()

Replace manual mutex_lock/unlock with guard(mutex) in raw.c receive_data(). This automates lock release on function exit, ensures that lock is released on early returns, and makes the code cleaner.

Please only use guard() logic with new code, or if you are fixing a bug. Making changes like this to existing code is not needed at all, it just causes unwanted churn for no good reason.
