From 509a02df44df8454b96da0b9bfcaa19f0a349df6 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 4 Oct 2013 17:37:09 +0200 Subject: [PATCH] Kind of revert "powerpc: 52xx: provide a default in mpc52xx_irqhost_map()" This more or less reverts commit 6391f697d4892a6f233501beea553e13f7745a23. Instead of adding an unneeded 'default', mark the variable to prevent the false positive 'uninitialized var'. The other change (fixing the printout) needs revert, too. We want to know WHICH critical irq failed, not which level it had.
