The %pe format specifier is designed to print error pointers. It prints a symbolic error name (eg. -EINVAL) and it makes the code simpler by omitting PTR_ERR(). This patch fixes this cocci report: ./i2c/ov9282.c:1133:3-10: WARNING: Consider using %pe to print PTR_ERR() Signed-off-by: Ricardo Ribalda <ribalda@chromium.org> Reviewed-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil+cisco@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.
