From 909b345665158323b44e9c8b70234dea3067685d Mon Sep 17 00:00:00 2001 From: Ryder Lee Date: Mon, 16 Apr 2018 10:33:47 +0800 Subject: [PATCH] mmc: mediatek: use of_device_get_match_data() The usage of of_device_get_match_data() reduce the code size a bit. Also, the only way to call msdc_drv_probe() is to match an entry in msdc_of_ids[], so of_id cannot be NULL.
