Subject: firewire: fix resetting of bus manager retry counter
X-Git-Tag: v2.6.29-rc1~187^2~1
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=d6f95a3d14dc403881b23ad268ec1e3600c4e6b4;p=linux-2.6-omap-h63xx.git

firewire: fix resetting of bus manager retry counter

An earlier change, maybe long ago, removed the copying of self_id_count
into card->self_id_count.  Since then each bus reset cleared
card->bm_retries even when it shouldn't.
