Subject[PATCH linux-next] drm/i915: Remove redundant assignments
Date
From: penghao luo <luo.penghao@zte.com.cn>

The assignment of variables will be overwritten later, so the
assignment here is meaningless.

The clang_analyzer complains as follows:

drivers/gpu/drm/i915/gem/i915_gem_userptr.c:291: warning:

Although the value stored to 'ret' is used in the enclosing expression,
the value is never actually read from 'ret’.
