From e65b52456bc3f60a176fece5e34e420c5a75bd16 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Mon, 31 Aug 2015 21:32:11 +0100 Subject: gdb/tui: Remove casts of NULL during assignment. In the following code: struct symbol *wsym = (struct symbol *) NULL; the cast of NULL is redundant, it adds noise, and is just one more thing to change if the type of wsym ever changes. There are a relatively small number of places in gdb where the above code pattern is used. Usually the cast is removed like this: struct symbol *wsym = NULL; This commit updates all the places within the gdb/tui directory where we cast NULL during assignment, removing the cast. gdb/ChangeLog: * tui/tui-data.c (win_with_focus): Remove cast of NULL pointer.
