From d9bfbb95ed598a09cf336adb0f190ee0ff802f0d Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 26 Nov 2015 14:00:47 +0200 Subject: mmc: sdio: Fix invalid vdd in voltage switch power cycle The 'ocr' parameter passed to mmc_set_signal_voltage() defines the power-on voltage used when power cycling after a failure to set the voltage. However, in the case of mmc_sdio_init_card(), the value passed has the R4_18V_PRESENT flag set which is not valid for power-on and results in an invalid vdd. Fix by passing the card's ocr value which does not have the flag.
