From bfcb2cc798a14230d22b6dd999e2e680623de622 Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 10 Jan 2012 15:10:15 -0800 Subject: [PATCH] checkpatch: catch all occurences of type and cast spacing errors per line Fix up type and cast spacing checks such that all occurences on a line are examined and reported. For example the line below has a valid cast and a bad type, but currently we check the cast first which is good and stop: u16* bar = (u16 *)baz; We will also only report one of the errors in this example: u16* bar = (u16*)bad; Move to iterating across all casts and all types, reporting any failure.
