Hi Prateek,
After breaking down the print msg based on your suggestion, checkpatch
gives a warning. There are no warnings reported with current version of
change. Even the fix suggested by checkpatch is aligned to what we have
right now. So I'll keep it like this, not push further changes as of now
and wait for the maintainers to pick the patch.

WARNING: quoted string split across lines
#57: FILE: kernel/sched/topology.c:2365:
+               pr_info_once("%s: Skipping topology span sanity check."
+                            " Use `sched_verbose` boot parameter to
enable it.\n",

total: 0 errors, 1 warnings, 14 lines checked
