[PATCH 2/5] mmc: sdhci-tegra: Use of_device_get_match_data() helper

From: Bean Huo
Date: Wed Feb 02 2022 - 13:07:06 EST


From: Bean Huo <beanhuo@xxxxxxxxxx>

Only the device data is needed,not the whole struct of_device_id.
Use of_device_get_match_data() instead of open coding of of_match_device().
