From 6bf789672ee8387fda08af1deeffd12126e60659 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 23 Apr 2014 09:58:27 -0500 Subject: [PATCH] Revert "serial: omap: unlock the port lock" 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.
