Subject: [PATCH 3.12 086/111] drivers: staging: dgap: move DG_NAME and DG_PART from "Makefile" to "dgap_driver.h"

From: Chen Gang <gang.chen@...anux.com>

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

===============

commit 6319c61aecc7acaf39a1dc0e81a8aac6a17499ee upstream.

Normally, the macros from command line are system specific macros (e.g
__linux, __KERNEL__ ...), and module own macros are usually defined in
their header files.

DG_NAME and DG_PART are driver 'dgap' owned macros which are used by
multiple files within driver, and need be defined in the driver main
header file.

So move DG_NAME and DG_PART to "dgap_driver.h", it not only can make
code clearer, but also can avoid compiling failure when EXTRA_CFLAGS
appended to make command line (e.g. "EXTRA_CFLAGS=-W").
