Takashi Iwai 574b59db65 ALSA: ak411x: Fix stall in work callback ... commit 4161b4505f1690358ac0a9ee59845a7887336b21 upstream. When ak4114 work calls its callback and the callback invokes ak4114_reinit(), it stalls due to flush_delayed_work(). For avoiding this, control the reentrance by introducing a refcount. Also flush_delayed_work() is replaced with cancel_delayed_work_sync(). The exactly same bug is present in ak4113.c and fixed as well.
