For reducing the global variable reference, keep snd_intelhad object in the context and pass it to each helper. It's a preliminary change for further cleanup. This also includes the simplification of the probe procedure: the LPE platform driver directly gets the created snd_intelhad object by hdmi_audio_probe(), and passes it to each helper and destructor, hdmi_audio_remove(). The hdmi_audio_probe() function doesn't call the back-registration any longer, which is fairly useless. The LPE platform driver initializes the stuff instead at the right place, and calls the wq after the object creation in the probe function itself. Signed-off-by: Takashi Iwai <tiwai@suse.de>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
