Subject: [PATCH 0/2] serial: imx: fix unbind/bind console

Hi,
here a couple of fixes to properly handle imx serial console
bind/unbind at runtime.

The patch from Stefan was already posted years ago
but never merged [1], however is still valid and it's
pretty easy to trigger the problem.

Francesco Dolcini (1):
  serial: imx: disable console clocks on unregister

Stefan Agner (1):
  serial: imx: fix crash when un/re-binding console
