From: Yunjian Wang <[email protected]>The issue is that a file descriptor at 0 is a valid one. Currently the file not found, the return value will be set to 0. As a result, it is impossible to distinguish between a correct descriptor and a failed return value. Fix it to return -ENOENT instead of 0.

I am unfamiliar with bus/fslmc code but i've taken a quick look, and i've noticed that there's another instance of get_group_fd() usage that you're not modifying - is that intentional?
