[REBASED PATCH RESEND 0/5 v2] Various cleanup

[David Weinehall]

This patch series aims to do some cleanup of our driver.
Patch 1, 2, and 4 should be fairly non-controversial.
Patch 3 and 5 does major cleanups of i915_sysfs and i915_debugfs,
respectively. Due to the nature of these patches they are rather
big, but that's mainly because they change the parameter passed
to macros that are used a lot.

While the secondary benefits of this patch series (the primary
of course being slightly cleaner code) might be a bit opaque,
a move to always passing dev_priv to our feature macros
(and thus allowing us to make those macros non-polymorphic)
will save more than 30kB.

That's still a bit down the road though, but I've got a full
patch series to accomplish this in a fairly straightforward
manner.

[REBASED PATCH RESEND 2/5 v2] 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.

v2: Replace the dev_to_drm_minor() macro with the inline function
    kdev_to_drm_minor().

[REBASED PATCH RESEND 3/5 v2] drm/i915: i915_sysfs.c cleanup

[David Weinehall]

Various cleanup for i915_sysfs.c; we now use dev_priv whenever
possible. The kdev_to_drm_minor() helper function has been
replaced by one that converts from struct device *
to struct drm_i915_private *.

We already have a seemingly identical helper (kdev_to_i915())
in i915_drv.h. But that one cannot be used here.
Unlike the version in i915_drv.h, this helper
reaches i915 through drm_minor.

v2: Rename kdev_to_i915_dm() to kdev_minor_to_i915() (Chris)

[REBASED PATCH RESEND 4/5 v2] 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.

v2: Fixed one more place missing in the previous patch set

[REBASED PATCH RESEND 5/5 v2] drm/i915: debugfs spring cleaning

[David Weinehall]

Just like with sysfs, we do some major overhaul.

Pass dev_priv instead of dev to all feature macros (IS_, HAS_,
INTEL_, etc.). This has the side effect that a bunch of functions
now get dev_priv passed instead of dev.

All calls to INTEL_INFO()->gen have been replaced with
INTEL_GEN().

We want access to to_i915(node->minor->dev) in a lot of places,
so add the node_to_i915() helper to accomodate for this.

Finally, we have quite a few cases where we get a void * pointer,
and need to cast it to drm_device *, only to run to_i915() on it.
Add cast_to_i915() to do this.

v2: Don't introduce extra dev (Chris)

v3: Make pipe_crc_info have a pointer to drm_i915_private instead of
    drm_device. This saves a bit of space, since we never use
    drm_device anywhere in these functions.

    Also some minor fixup that I missed in the previous version.

v4: Changed the code a bit so that dev_priv is passed directly
    to various functions, thus removing the need for the
    cast_to_i915() helper. Also did some additional cleanup.

v5: Additional cleanup of newly introduced changes.

Re: [REBASED PATCH RESEND 5/5 v3] drm/i915: debugfs spring cleaning

[David Weinehall]

Just like with sysfs, we do some major overhaul.

Pass dev_priv instead of dev to all feature macros (IS_, HAS_,
INTEL_, etc.). This has the side effect that a bunch of functions
now get dev_priv passed instead of dev.

All calls to INTEL_INFO()->gen have been replaced with
INTEL_GEN().

We want access to to_i915(node->minor->dev) in a lot of places,
so add the node_to_i915() helper to accomodate for this.

Finally, we have quite a few cases where we get a void * pointer,
and need to cast it to drm_device *, only to run to_i915() on it.
Add cast_to_i915() to do this.

v2: Don't introduce extra dev (Chris)

v3: Make pipe_crc_info have a pointer to drm_i915_private instead of
    drm_device. This saves a bit of space, since we never use
    drm_device anywhere in these functions.

    Also some minor fixup that I missed in the previous version.

v4: Changed the code a bit so that dev_priv is passed directly
    to various functions, thus removing the need for the
    cast_to_i915() helper. Also did some additional cleanup.

v5: Additional cleanup of newly introduced changes.

v6: Rebase again because of conflict.
