From: Sudip Mukherjee Date: Tue, 23 Jun 2015 13:29:40 +0000 (+0530) Subject: USB: mos7720: rename registers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee5729ece70b2dacd8fc6ed928f9f81ced9f380e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git USB: mos7720: rename registers Some of the register names defined here are matching with registers defined in other places. Like DCR is defined here and DCR is also a register in mn10300 architecture. So when we are building this with mn10300, build fails. To avoid we rename all the registers.
