[PATCH 1/3] drm: property: One function call less in drm_property_create() after error detection

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

The kfree() function was called in one case by the
drm_property_create() function during error handling
even if the passed data structure member contained a null pointer.
This issue was detected by using the Coccinelle software.

Thus use another label.
