Seems no need add another patch, just modify this patch as below:
diff --git a/drivers/usb/mtu3/mtu3_trace.h b/drivers/usb/mtu3/mtu3_trace.h index a09deae1146f..03d2a9bac27e 100644 --- a/drivers/usb/mtu3/mtu3_trace.h +++ b/drivers/usb/mtu3/mtu3_trace.h @@ -18,18 +18,16 @@
#include "mtu3.h"
-#define MTU3_MSG_MAX 256 - TRACE_EVENT(mtu3_log, TP_PROTO(struct device *dev, struct va_format *vaf), TP_ARGS(dev, vaf), TP_STRUCT__entry( __string(name, dev_name(dev)) - __dynamic_array(char, msg, MTU3_MSG_MAX) + __vstring(msg, vaf->fmt, vaf->va) ), TP_fast_assign( __assign_str(name, dev_name(dev)); - vsnprintf(__get_str(msg), MTU3_MSG_MAX, vaf->fmt, *vaf- >va); + __assign_vstr(msg, vaf->fmt, vaf->va); ), TP_printk("%s: %s", __get_str(name), __get_str(msg)) );
remove below two lines " -#define MTU3_MSG_MAX 256 - " Thanks
