All switch (pipe->asd->streaming) cases in atomisp_pipe_check() are either no-ops or never happen: 1. ATOMISP_DEVICE_STREAMING_DISABLED already is a no-op 2. The videobuf2 core guarantees that when we are streaming vb2_is_busy() returns true. So the ATOMISP_DEVICE_STREAMING_ENABLED case is already handled by the if above the switch (pipe->asd->streaming). 3. After recent changes pipe->asd->streaming is only ever set to ATOMISP_DEVICE_STREAMING_STOPPING in atomisp_assert_recovery_work() and that function holds isp->mutex and always transitions the streaming state to ATOMISP_DEVICE_STREAMING_DISABLED or ATOMISP_DEVICE_STREAMING_ENABLED before releasing the mutex. So atomisp_pipe_check() never sees ATOMISP_DEVICE_STREAMING_STOPPING. Remove the entire switch-case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
