[PATCH 4.14 08/89] mmc: renesas_sdhi_internal_dmac: fix #define RST_RESERVED_BITS

From: Greg Kroah-Hartman
Date: Fri Sep 07 2018 - 17:26:42 EST


4.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>

commit 9faf870e559a710c44e747ba20383ea82d8ac5d2 upstream.

The DM_CM_RST register actually has bits 0-31 defaulting to 1s and bits
32-63 defaulting to 0s -- fix off-by-one in #define RST_RESERVED_BITS.
