had_enable_audio_int() came from the LPE audio shell set_caps callback with ENABLE_INT and DISABLE_INT caps. I interpreted as these correspond to enabling / disabling the audio interface, but the actual implementation is only to clear (send ACK) to both BUFFER_DONE and BUFFER_UNDERRUN interrupts unconditionally. And, there is no counterpart, DISABLE_INT, code at all. For avoiding the further misunderstanding, rename the function to the more fitting one, had_ack_irqs(), and drop the calls with enable=false in allover places. There is no functional changes at all. After this patch, there is only one caller at the PCM trigger start. Then it's doubtful whether this call is still really needed or not; I bet it not, but let's stay in the safer side for now and keep it as was. Signed-off-by: Takashi Iwai <tiwai@suse.de> |

README
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.
