From 406df85345f942d9348443983d81a01e013e920b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 22 May 2020 18:19:08 +0200 Subject: mmc: fsl_esdhc: Fix SDR104 and HS200 support The 3V3/1V8 switching could never have worked on any of the iMXes ever since 51313b49f2 ("mmc: fsl_esdhc: support SDR104 and HS200"), because that commit uses priv->vqmmc_dev when switching voltages on mode switch, while local vqmmc_dev in probe to store the regulator pointer. Those are two different variables with the same name. So the priv->vqmmc_dev was always NULL and thus voltage switch between modes never really suceeded. Fix this by assigning priv->vqmmc_dev with value of the vqmmc_dev in probe.
