The config parameters buffer is already validated in pisp_be_validate_config() at .buf_prepare() time. However some of the same validations are also performed at pispbe_schedule() time. In particular the function checks that: 1) config.num_tiles is valid 2) At least one of the BAYER or RGB input is enabled The input config validation is already performed in pisp_be_validate_config() and while job.hw_enables is modified by pispbe_xlate_addrs(), the function only resets the input masks if - there is no input buffer available, but pispbe_prepare_job() fails before calling pispbe_xlate_addrs() in this case - bayer_enable is 0, but in this case rgb_enable is valid as guaranteed by pisp_be_validate_config() - only outputs are reset in rgb_enable For this reasons there is no need to repeat the check at pispbe_schedule() time. The num_tiles validation can be moved to pisp_be_validate_config() as well. As num_tiles is a u32 it can'be be < 0, so change the sanity check accordingly.

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 reStructuredText 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.
