If anyone has any objections, please let me know. ------------------ From: Marc Kleine-Budde commit f901b6bc404b67d96eca739857c097e022727b71 upstream. Thias patch fixes a define conflict between the SH architecture and the sja1000 driver: drivers/net/can/sja1000/sja1000.h:59:0: warning: "REG_SR" redefined [enabled by default] arch/sh/include/asm/ptrace_32.h:25:0: note: this is the location of the previous definition A SJA1000_ prefix is added to the offending sja1000 define only, to make a minimal patch suited for stable. A later patch will add a SJA1000_ prefix to all defines in sja1000.h.
