Cover letter [PATCH v2 0/2] Fix no_console_suspend for PNP serial consoles

Hi Greg and Rafael,

This v2 of the earlier series submitted back in Nov addresses Rafael's comments, specifically:

* Adds PNP_CONSOLE flag, which disables the pnp protocol's suspend() and disable() methods.

This greatly simplifies the PNP serial driver patch since the existing pnp device capabilities does not need to be saved and restored now.

Note that it was necessary to continue to use macros, since struct pnp_protocol is anonymous.

Regards,
