From e396de684ebea31bde476423edcb087432f46729 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20L=C3=BCtke-Stetzkamp?= Date: Wed, 25 Apr 2018 08:43:18 +0200 Subject: [PATCH] staging: mt7621-mmc: Fix calculation typo in msdc_init_gpd_bd MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When refactoring the function msdc_init_gpd_bd, an error in the calculation of the bd.next address was introduced. The offset has to be added to the base address, not multiplied.
