From fbb31330f9b00bf62fe126a1ea118c02389b06f0 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 22 Sep 2020 19:22:53 +0200 Subject: mmc: renesas_sdhi: drop local flag for tuning The MMC core has now a generic check if some tuning is in progress. Its protected area is a bit larger than the custom one in this driver but we concluded that this works equally well for the intended case. So, drop the local flag and switch to the generic one.
