[PATCH v3 0/6] Fix issues reported by klocwork

[Aleksei Gimbitskii]

The klocwork static code analyzer found 11 critical issues and 7 error
issues in GVT-g source code. After the analyzation, one critical issue
and 6 "errors" was concluded as harmless. This patchset fixes other
cases, which might cause potential issues in future.

v3:
- Remove typedef and let the enumeration starts from zero.

V2:
- Print some error messages if page table type is invalid. (Colin Xu)
- Increase the size of the buffer. (Colin Xu)
- Initialize fb_info.obj in vgpu_get_plane_info(). (Colin Xu)

Aleksei Gimbitskii (6):
  drm/i915/gvt: Remove typedef and let the enumeration starts from zero
  drm/i915/gvt: Do not copy the uninitialized pointer from fb_info
  drm/i915/gvt: Use snprintf() to prevent possible buffer overflow.
  drm/i915/gvt: Check if cur_pt_type is valid
  drm/i915/gvt: Assign NULL to the pointer after memory free.
  drm/i915/gvt: Check if get_next_pt_type() always returns a valid value
