[S390] irq: simple coding style change
Heiko Carstens [Wed, 11 Apr 2012 12:28:09 +0000 (14:28 +0200)]
Use braces for if/else/list_for_each_entry bodies if the body consists
of more than a single line. Otherwise I get confused and check if there
is something broken whenever I see these code snippets.
