#     powerpc/perf: Convert fsl_emb notifier to state machine callbacks
#     
#       CC      arch/powerpc/perf/core-fsl-emb.o
#     arch/powerpc/perf/core-fsl-emb.c:675:6: error: no previous prototype for 'hw_perf_event_setup' [-Werror=missing-prototypes]
#       675 | void hw_perf_event_setup(int cpu)
#           |      ^~~~~~~~~~~~~~~~~~~
#     
#     Looks like fsl_emb was completely missed by commit 3f6da3905398 ("perf:
#     Rework and fix the arch CPU-hotplug hooks")
#     
#     So, apply same changes as commit 3f6da3905398 ("perf: Rework and fix
#     the arch CPU-hotplug hooks") then commit 57ecde42cc74 ("powerpc/perf:
#     Convert book3s notifier to state machine callbacks")
#     
#     While at it, also fix following error:
#     
#     arch/powerpc/perf/core-fsl-emb.c: In function 'perf_event_interrupt':
#     arch/powerpc/perf/core-fsl-emb.c:648:13: error: variable 'found' set but not used [-Werror=unused-but-set-variable]
#       648 |         int found = 0;
#           |             ^~~~~
#     
#     Fixes: 3f6da3905398 ("perf: Rework and fix the arch CPU-hotplug hooks")
