[PATCH 0/3] serial: Use of_device_get_match_data

[Tang Bin]

Hi all:

This patch series replace 'of_match_device' with
'of_device_get_match_data', to make code cleaner and better.

Thanks

[PATCH 1/3] serial: 8250_ingenic: Use of_device_get_match_data

[Tang Bin]

Retrieve OF match data, it's better and cleaner to use
'of_device_get_match_data' over 'of_match_device'.
