2020-12-09scsi: ufs-mediatek: Use correct path to fix compile errorZhen Lei
When the kernel is compiled with allmodconfig, the following error is reported: In file included from drivers/scsi/ufs/ufs-mediatek-trace.h:36:0, from drivers/scsi/ufs/ufs-mediatek.c:28: ./include/trace/define_trace.h:95:42: fatal error: ./ufs-mediatek-trace.h: No such file or directory #include TRACE_INCLUDE(TRACE_INCLUDE_FILE) The comment in include/trace/define_trace.h specifies that: TRACE_INCLUDE_PATH: Note, the path is relative to define_trace.h, not the file including it. Full path names for out of tree modules must be used. So without "CFLAGS_ufs-mediatek.o := -I$(src)", the current directory "." is "include/trace/", the relative path of ufs-mediatek-trace.h is "../../drivers/scsi/ufs/".
