I think this is a simple fix. The declaration needs to be:
int bi = -1, ci = -1;

Hello,
I am attempting to compile the kernel and getting blocked by the following
error:
../../../../kern/subr_devsw.c:424:29: error: 'bi' may be used uninitialized
in this function [-Werror=maybe-uninitialized]

I am using NetBSD 9.2 on an amd64 system, and I'm attempting to build the wifi
branch of src-draft. Here is my gcc -v output:

Thread model: posix
gcc version 7.5.0 (nb4 20200810)
Am I using the wrong version of gcc or something? All of my packages are up to
date and it looks like this is the result of a commit
from back in March and I haven't seen anyone else mention being unable to build
due to this.
Thanks for your help,
James
