The open() fops support two types of devices: "acc" and normal ones. the acc works on a different way, using a different pipe struct. Not sure yet if it would make sense to setup a run_mode there. Also, As default_run_mode exists only on normal modes, we can simplify the logic to check if the device is in normal mode. That solves this warning: ../drivers/staging/media/atomisp/pci/atomisp_fops.c:904 atomisp_open() warn: variable dereferenced before check 'asd' (see line 807) Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
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.
