Subject: serial: tegra: Use of_device_get_match_data
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a6a65f9ee0937d02e8084ee1ed305e38aae848e6;p=linux.git

serial: tegra: Use of_device_get_match_data

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