From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 3eda901995371d390ef82d0b6462f4ea8efbcfdf upstream.
These error paths returned 1 on failure, instead of a negative error
code. This would lead to an Oops in the caller. A second problem is
that the check for "if (ret != -ENODATA)" did not work because "ret" was
set to 1.
Fixes: 5785dd7a8ef0 ("drm/msm: Fix duplicate gpu node in icc summary")
