Subject: Initialize ieee1394 early when built in
X-Git-Tag: v2.6.19-rc1~644^2~22
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8df4083c5291b3647e0381d3c69ab2196f5dd3b7;p=linux-2.6

Initialize ieee1394 early when built in

This makes debugging with firescope easier.

Signed-off-by: Andi Kleen <ak@suse.de> (original patch)

Update:
 - no need for #ifdef MODULE
 - add comment in ieee1394_core, more verbose comment in ohci1394
