checkpatch: check networking specific block comment style
In an effort to get fewer checkpatch reviewer corrections, add a
networking specific style test for the preferred networking comment style.
/* The preferred style for block comments in
* drivers/net/... and net/... is like this
*/
These tests are only used in net/ and drivers/net/
Tested with:
$ cat drivers/net/t.c
/* foo */
/*
* foo
*/
/* foo
*/
/* foo
* bar */
$ ./scripts/checkpatch.pl -f drivers/net/t.c
WARNING: networking block comments don't use an empty /* line, use /* Comment...
#4: FILE: net/t.c:4:
+
+/*
WARNING: networking block comments put the trailing */ on a separate line
#12: FILE: net/t.c:12:
+ * bar */
total: 0 errors, 2 warnings, 12 lines checked
