Amadeusz Sławiński 1023af0c06 ALSA: hdac: fix memory release for SST and SOF drivers ... [ Upstream commit 6d647b736a6b1cbf2f8deab0e6a94c34a6ea9d60 ] During the integration of HDaudio support, we changed the way in which we get hdev in snd_hdac_ext_bus_device_init() to use one preallocated with devm_kzalloc(), however it still left kfree(hdev) in snd_hdac_ext_bus_device_exit(). It leads to oopses when trying to rmmod and modprobe. Fix it, by just removing kfree call. SOF also uses some of the snd_hdac_ functions for HDAudio support but allocated the memory with kzalloc. A matching fix is provided separately to align all users of the snd_hdac_ library.
