From 4c3965aa995bd31d0454fa5e20314f1eeead8413 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 6 Apr 2020 13:43:37 +0200 Subject: [PATCH] mmc: au1xmmc: Drop redundant code in au1xmmc_send_command() The in-parameter "wait" is always set to 0 by the caller, hence just drop it and its corresponding code.
