From 9b7bbe1085eb2b0f2d5d81f4116772cb2af497a4 Mon Sep 17 00:00:00 2001 From: Shashidhar Hiremath Date: Fri, 29 Jul 2011 08:49:50 -0400 Subject: [PATCH] mmc: dw_mmc: Fix mask in IDMAC_SET_BUFFER1_SIZE macro The mask used inside this macro was assuming Buffer_Size1's [BS1's] width to be 14 bits, it is actually 13 bits. Modify masks used in IDMAC_SET_BUFFER1_SIZE such that they use only 13 bits instead of current 14.
