Check patch errors as below :
ERROR: Macros with complex values should be enclosed in parentheses
#121: FILE: drivers/hwtracing/coresight/coresight-etm4x.h:153:
+#define CASE_READ(res, x) \
+ case (x): { (res) = read_etm4x_sysreg_const_offset((x)); break; }
ERROR: trailing statements should be on next line
#122: FILE: drivers/hwtracing/coresight/coresight-etm4x.h:154:
+ case (x): { (res) = read_etm4x_sysreg_const_offset((x)); break; }
This one may be fixed by splitting the above line to multpile lines.
But the first one above is not easy to fix. And there are more users
of such constructs elsewhere.
