[PATCH 00/35] treewide trivial patches converting pr_warning to pr_warn
There are ~4300 uses of pr_warn and ~250 uses of the older
pr_warning in the kernel source tree.
Make the use of pr_warn consistent across all kernel files.
This excludes all files in tools/ as there is a separate
define pr_warning for that directory tree and pr_warn is
not used in tools/.
Done with 'sed s/\bpr_warning\b/pr_warn/' and some emacsing.
