commit 2bb3729d8db44ffefa2eee4465574baf2ccfaed8 Author: Stefan Reinauer reinauer@chromium.org Date: Tue Apr 23 15:23:15 2013 -0700
Unify and clean up remaining INT15 handlers
Some handlers still had 2 variants, others were incorrectly guarded by CONFIG_ variables. This patch straightens them out.
This does not touch the siemens/sitemp_g1p1 which provides an interestingly complex solution for the int15 handler.
