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


From: Arnd Bergmann <a...@arndb.de>

commit b41c29b0527c7fd6a95d0f71274abb79933bf960 upstream.

The default __UNIQUE_ID macro in compiler.h fails to work for some drivers:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:615:1: error: 
redefinition of
BRCMF_FW_NVRAM_DEF(4354, "brcmfmac4354-sdio.bin", "brcmfmac4354-sdio.txt");

This adds a copy of the version we use for gcc-4.3 and higher, as the same
one works with all versions of clang that I could find in svn (2.6 and higher).
