All ov2740_check_hwcfg() error-exit paths already log a detailed reason, logging a second generic "failed to check HW configuration" error is not useful, drop this. The one exception is the -EPROBE_DEFER exit on fwnode_graph_get_next_endpoint() returning NULL. Call dev_err_probe() there to register the reason for deferring the probe, this is used if the endpoint is still not there after 30 seconds, e.g. : i2c-INT3474:00: deferred probe pending: waiting for fwnode graph endpoint Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Bingbu Cao <bingbu.cao@intel.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
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.
