For this patch, though, it seems like we should just update the dates
instead of removing them.

If I look at the last 1000 "^+.*Copyright" lines added to the kernel,
997 of them have a year.  So, weird or not, it's a pretty standard
convention.  We'd need a slightly more broad conversation before we
decide to nix these dates.

Pure speculation: Copyright protection, at least in the US, is not
forever.  I _think_ it's 75 years or something.  That protection starts
when the work is created and is independent of when it gets merged into
Linux.  So, if we did something weird like merge a driver written 10
years ago, it would only be protected for 65 more years after we merge
it.  In other words, git history _might_ be irrelevant for copyright
protection.
