Last I looked the diffstat for comma -> semicolon was:

234 files changed, 509 insertions(+), 509 deletions(-)

So it would be nearly 1 patch per individual file,

Greg KH does send hundreds of patches for -stable at a time.

So, maybe or maybe not send them all at once.
Maybe send it in batches of 25 or so.

There's no single right way to do this.

Maybe put up a git tree somewhere and let the
kernel-robot test compilation.

(A nicety might be for the kernel-robot to have some
 option to test pre and post compilation object code
 differences with an optional report)

When I automated 491 patches for /* fallthrough */ to
fallthrough;, the robot caught a couple problems which
was great.

https://repo.or.cz/linux-2.6/trivial-mods.git/shortlog/refs/heads/20200310_fallthrough_2

I only posted the first ~30 patches though with
about 50% acceptance. Gustavo Silva picked up the
effort and did a great job.  Eventually, a single
treewide patch was posted and accepted by Linus for
this though after dozens of individual patches went
through various maintainer trees:

$ git log --shortstat -1 df561f6688fe
commit df561f6688fef775baa341a0f5d960becd248b11
Author: Gustavo A. R. Silva <gustavoars@kernel.org>
Date:   Sun Aug 23 17:36:59 2020 -0500

    treewide: Use fallthrough pseudo-keyword
    
    Replace the existing /* fall through */ comments and its variants with
    the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
    fall-through markings when it is the case.
