From 5e3d20a68f63fc5a310687d81956c3b96e488b84 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 4 Jul 2010 00:02:26 +0200 Subject: init: Remove the BKL from startup code I have shown by code review that no driver takes the BKL at init time any more, so whatever the init code was locking against is no longer there and it is now safe to remove the BKL there.
