This reverts commit f5f3a2c656 ("staging: comedi: cb_pcidas64: change
params to external_ai_queue_in_use()"). The
`external_ai_queue_in_use()` was being called from `ao_cmd()` with
pointers to the "write" subdevice and AO command, but is supposed to
check whether the external AI queue is currently in use by the "read"
subdevice and AI command. In fact, the return value always indicated
that the external AI queue was not in use in this case (because the AO
command's channel list is sequential), so was fairly useless. (However,
even before the reverted commit, the logic in
`external_ai_queue_in_use()` was wrong. That will be corrected in a
subsequent commit.)

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.
