The first assignment is not used. In order to keep the code style
consistency of the whole file, the first 'data' assignment should be
deleted.
The clang_analyzer complains as follows:
drivers/gpu/drm/amd/amdgpu/gfx_v6_0.c:2608:10: warning:
Although the value storedto 'offset' is used in the enclosing expression,
the value is never actually read from 'offset'.
