This reverts commit 0324a821029e1f54e7a7f8fed48693cfce42dc0e.
That commit tried to fix a deadlock problem when using
hci_ldisc, but it turns out the bug was in hci_ldsic
all along where it was calling ->write() from within
->write_wakeup() callback.
The problem is that ->write_wakeup() was called with
port lock held and ->write() tried to grab the same
port lock.
Should this and the next patch be earlier in the series
as a fix for the v3.15-rc cycle? Should they be cc: stable
as well?
Well, right now the other fix has had _zero_ testing
so not really a -stable candidate just yet.
