[PATCH 2/2] checkpatch: catch all occurances of type and cast spacing errors per line

From: Andy Whitcroft
Date: Thu Dec 01 2011 - 04:33:30 EST


Fix up type and cast spacing checks such that all occurances 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.
