drm: Introduce drm_property_blob_{get,put}()

2017-02-28T15:16:46+00:00

For consistency with other reference counting APIs in the kernel, add
drm_property_blob_get() and drm_property_blob_put() to reference count
DRM blob properties.

Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.

A semantic patch is provided that can be used to convert all drivers to
the new helpers.

drm: Introduce drm_gem_object_{get,put}()

2017-02-28T15:16:43+00:00

For consistency with other reference counting APIs in the kernel, add
drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked
variant of the latter, to reference count GEM buffer objects.

Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.

The existing semantic patch for the DRM subsystem-wide conversion is
extended to account for these new helpers.

Coccinelle: misc: Add support for devm variant in all modes

2016-12-11T11:08:26+00:00

Add missing support for the devm_request_threaded_irq in
the rules of context, report and org modes.

Misc:
----
To be consistent with other scripts, change confidence level
of the script to 'Moderate'.

Coccinelle: misc: Improve the result given by context mode

2016-12-11T11:08:26+00:00

To eliminate false positives given by the context mode, add
necessary arguments for the function request_threaded_irq.

Coccinelle: misc: Improve the matching of rules

2016-12-11T11:08:26+00:00

Currently because of the left associativity of the operators, pattern
IRQF_ONESHOT | flags does not match with the pattern when we have more
than one flag after the disjunction. This eventually results in giving
false positives by the script. This patch eliminates these FPs by
improving the rule.

Coccinelle: flag conditions with no effect

2016-10-11T07:57:17+00:00

Report code constructs where the if and else branch are functionally
identical. In cases where this is intended it really should be
documented - most reported cases probably are bugs.
