From e9705a77f50c1fd52356f4f0e515455273aae416 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 7 Jul 2007 03:38:51 +0900 Subject: [PATCH] fb: pvr2fb: Fix up section mismatch warnings. A few minor things were broken here. fix and var screeninfo should have been __devinitdata, board_list[] gets renamed to board_driver[] so the modpost matching does the right thing, and we properly discard some of the unused exit sections.
