Subject: s390/diag: add a s390 prefix to the diagnose trace point
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=230ccb370f8f95b2600a1fce90ceb8ee70a15dbc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/diag: add a s390 prefix to the diagnose trace point

Documentation/trace/tracepoints.txt states that the naming scheme
for tracepoints is "subsys_event" to avoid collisions. Rename
the 'diagnose' tracepoint to 's390_diagnose'.
