#     Merge tag 'trace-v5.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull nds32 tracing fix from Steven Rostedt:
#      "Fix nds32le build when DYNAMIC_FTRACE is disabled
#     
#       A randconfig found that nds32le architecture fails to build due to a
#       prototype mismatch between a ftrace function pointer and the function
#       it was to be assigned to. That function pointer prototype missed being
#       updated when all the ftrace callbacks were updated"
#     
#     * tag 'trace-v5.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
#       ftrace/nds32: Update the proto for ftrace_trace_function to match ftrace_stub
