Yes, but the analysis says nothing about what uart_break_ctl() itself might do, so by itself, it provides no guarantee for break_ctl(). That was my sticking point since somebody clearly put that line in there for a reason. Looking at the code, it's pretty obvious that uart_break_ctl() isn't acquiring any spinlocks. The documentation line in question has been there, unchanged, since the beginning of the Git era. The patch is obviously fine, and I've applied it, but I did tweak the changelog some.
