[RESEND] drm/msm/dpu: Delete a variable initialisation before a null pointer check in two functions

[Markus Elfring]

>>> The address of a data structure member was determined before
>>> a corresponding null pointer check in the implementation of
>>> the functions “dpu_hw_pp_enable_te” and “dpu_hw_pp_get_vsync_info”.
>>>
>>> Thus avoid the risk for undefined behaviour by removing extra
>>> initialisations for the variable “c” (also because it was already
>>> reassigned with the same value behind this pointer check).

> There is no undefined behavior here.
Will any software development concerns evolve further also according to
undesirable null pointer dereferences?
