Andrew Morton 57d4810ea0 revert "x86, serial: convert legacy COM ports to platform devices" ... Revert 7e92b4fc34. It broke Sébastien Dugué's machine and Jeff said (persuasively) This seems like it will break decades-long-working stuff, in favor of breaking new ground in our favorite area, "trusting the BIOS." It's just not worth it for serial ports, IMO. Serial ports are something that just shouldn't break at this late stage in the game. My new Intel platform boxes don't even have serial ports, so I question the value of messing with serial port probing even more... because... just wait a year, and your box won't have a serial port either! :) I certainly don't object to the use of platform devices (or isa_driver), but the probe change seems questionable. That's sorta analagous to rewriting the floppy driver probe routine. Sure you could do it... but why risk all that damage and go through debugging all over again? It seems clear from this report that we cannot, should not, trust BIOS for something (a) so simple and (b) that has been working for over a decade. Much discussion ensued and we've decided to have another go at all of this.
