The atomisp firmware contains a number of different pipeline binaries inside its firmware file and the driver selects the right one depending on the selected pipeline configuration. Sometimes (e.g. when the selected output resolution is too big) it fails to find a binary. This happens especially when adding support for new sensors. Improve the logging when this happens to make debugging easier: 1. Replace ia_css_debug_dtrace(IA_CSS_DEBUG_TRACE, ...) with standard dev_dbg() calls so that the logs can be enabled with dyndbg 2. Do not dump_stack() when this fails, doing so adds no useful extra info 3. With the dump_stack() call gone, remove the wrapper and rename __ia_css_binary_find() to ia_css_binary_find() 4. On error use dev_err() instead of dev_dbg() so that when things fail it is clear why they fail without needing to enable dyndbg Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20240902095229.59059-3-hdegoede@redhat.com 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 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.
