Subject: sparc32: Fix might-be-used-uninitialized warning in do_sparc_fault().
From: David S. Miller <[email protected]>
[ Upstream commit c816be7b5f24585baa9eba1f2413935f771d6ad6 ]
When we try to handle vmalloc faults, we can take a code
path which uses "code" before we actually set it.
Amusingly gcc-3.3 notices this yet gcc-4.x does not.
