[PATCH 0/4] Various cleanup

[David Weinehall]

To improve consistency in the driver, and to pave the way for
further cleanup patches, do various bits of tidying.

[PATCH 2/4] drm/i915: Consistent struct device naming

[David Weinehall]

We currently have a mix of struct device *device, struct device *kdev,
and struct device *dev (the latter forcing us to refer to
struct drm_device as something else than the normal dev).

To simplify things, always use kdev when referring to struct device.

[PATCH 3/4] drm/i915: Consistent drm_minor use

[David Weinehall]

Use consistent naming for drm_minor, and always use kdev_to_drm_minor()
to convert kdev to drm_minor.

[PATCH 4/4] drm/i915: pdev cleanup

[David Weinehall]

In an effort to simplify things for a future push of dev_priv instead
of dev wherever possible, always take pdev via dev_priv where
feasible, eliminating the direct access from dev. Right now this
only eliminates a few cases of dev, but it also obviates that we pass
dev into a lot of functions where dev_priv would be the more obvious
choice.

kdev may be confused with kdev_t, but seems reasonable due to kobj.

This patch is an improvement, so
Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

but I was wondering if

struct device *dev;
struct drm_device *drm;
struct i915_device *i915;

(struct i915_device is move apt now than drm_i915_private due to the
subclassing)

made more sense as a longterm goal?

I would have gone with struct drm_minor *minor, since there is no
confusion here (and dminor is a note ;)

Had you made kdev_to_drm_minor() typesafe (inline function) then I would
have classed it as an overall improvement and just grumbled about the
choice of name. As it stands, it doesn't make me feel the code is
substantially improved.

I'd vote for this scheme.

I think depending on if we end up with kdev or dev, then match with
dminor/minor.

In the driver,

30 out of 52 struct device * decls use "dev".

1233 out of 1251 struct drm_device * decls use "dev".

2112 out of 2154 struct drm_i915_private * decls use "dev_priv".

By all means change struct device *dev to something else, like kdev, or
whatever.

But do we really not have better things to do than come up with ways to
create tons of rename churn, increasing the cognitive burden of
developers, forcing rebases of tons of in-flight code making it harder
to get code in, creating conflicts for backporting fixes, and so on?

I'm firmly behind sticking with struct drm_i915_private *dev_priv and
struct drm_device *dev.

Jani.
