Then please say so in the commit log. Something like,

Fix commit 2dea53bf57783f243c892e99c10c6921e956aa7e,
"serial: of-serial: add PM suspend/resume support", which
disables the uart clock on suspend, but also causes a hardware
hang on register access if no_console_suspend command line option
is used.
