[PATCH] autofs-5.1.9 - fix ldap_parse_page_control() check

[David Disseldorp]

The final @cookie parameter should be a struct berval ** type. The
check currently fails when -Werror=incompatible-pointer-types is set:

conftest.c: In function 'main':

Thanks David, looks ok to me, will have a closer look and (I expect) 
will apply it.

Thanks for the feedback Ian. Is there anything holding this one up from
being merged?

Cheers, David

No, only me, actually I want to do a release but (just a couple of days 
ago) I was thinking I need

to push this and a couple of other patches to the repo. before I start 
the round of testing.


I have a bit to do (unrelated to this) before I get to it so sorry for 
the hold up.

I wouldn’t wrap the lines of the pasted parts, and use a more specific 
commit message summary instead of just *fix … check*. Maybe:

     ldap_parse_page_control(): Use correct type for @cookie

I'm fine with it either way, but I think the commit summary should
indicate that it's the config-time ldap_parse_page_control() call that's
problematic, not the modules/lookup_ldap.c invocation.
@Ian: feel free to update the commit message as you see fit.
