* [PATCH] mxser_new: correct tty driver nameJiri Slaby2006-12-081-1/+1
| | | | | | | | | | Mxser tty driver name should be ttyMI, not ttyM. Correct this in mxser_new to avoid conflicts with isicom driver, which is ttyM.

* [PATCH] Char: mxser_new, pci probingJiri Slaby2006-12-081-87/+88
| | | | | | | | | | | Finally, the intention of the patch serie: PCI probing for this driver. add pci_driver structure, (un)register it and add some stuff, which this needs. Remove pdev pointer from board structure, because it's no longer needed.
