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.

struct drm_device specific drm_WARN* macros include device information
in the backtrace, so we know what device the warnings originate from.
Prefer drm_WARN_ON over WARN_ON.
Conversion is done with below sementic patch:
@@
identifier func, T;
@@
func(...) {
...
struct drm_i915_private *T = ...;
<+...
-WARN_ON(
+drm_WARN_ON(&T->drm,
...)
...+>
}
@@
identifier func, T;
@@
func(struct intel_digital_port *T,...) {
+struct drm_i915_private *i915 = to_i915(T->base.base.dev);
<+...
-WARN_ON(
+drm_WARN_ON(&i915->drm,
...)
...+>
}
changes since v1:
- Add i915 local variable and use it in drm_WARN_ON (Jani)
