Merge tag 'staging-6.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver fix from Greg KH:
"Here is a single staging driver fix for 6.16-rc4. It resolves a build
error in the rtl8723bs driver for some versions of clang on arm64 when
checking the frame size with -Wframe-larger-than.

It has been in linux-next for a while now with no reported issues"
