checkpatch: always check block comment styles
Some of the block comment tests that are used only for networking are appropriate for all patches. For example, these styles are not encouraged: /* block comment without introductory * */ and /* * block comment with line terminating */ Remove the networking specific test and add comments. There are some infrequent false positives where code is lazily commented out using /* and */ rather than using #if 0/#endif blocks like: /* case foo: case bar: */ case baz: Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
