> Call mutex_unlock() before returning an error in ee1004_probe() Under which circumstances would you become interested to apply a statement like “guard(mutex)(&ee1004_bus_lock);”? https://elixir.bootlin.com/linux/v6.10-rc7/source/include/linux/mutex.h#L196 Would you like to refer to the function name “ee1004_probe” in the summary phrase?
