From a2f3453ebc64b1ebe094aeaf83f9e67896f90ac3 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Thu, 27 Apr 2017 16:58:14 -0500 Subject: [PATCH] coccinelle: Add script to remove useless QObject casts We have macros in place to make it less verbose to add a subtype of QObject to both QDict and QList. While we have made cleanups like this in the past (see commit fcfcd8ffc, for example), having it be automated by Coccinelle makes it easier to maintain. The script is separate from the cleanups, for ease of review and backporting. A later patch will then add further possible cleanups.
