[PATCH] checkpatch: avoid warning on page flag acessors

[Cody P Schafer]

Using Page*() triggers a camelcase warning, but shouldn't.

Introduced by be987d9f80354e2e919926349282facd74992f90, which added the
other Page flag users.

Pipe ('|') at the end of a grouping doesn't cause the grouping to match
an emtpy string, use ? after the grouping instead to get the desired
behavior.

[PATCH v2] checkpatch: avoid warning on page flag acessors

[Cody P Schafer]

Using Page*() triggers a camelcase warning, but shouldn't.

be987d9f80354e2e919926349282facd74992f90 added a spurious '"' (double
quote) breaking the regex.

Appologies for the noise, I updated my commit message but not the patch in the previous version.

I think you need to delete the ", leave the | and remove the ?
Dunno where that " came from.

And using sha1s in format-patch means I have to actually copy the new ones. (Again, sorry).
