[PATCH] drm/msm/a4xx: fix error handling in a4xx_gpu_init()

[Dan Carpenter <dan.carpenter@oracle.com>]

This code returns 1 on error instead of a negative error.  It leads to
an Oops in the caller.  A second problem is that the check for
"if (ret != -ENODATA)" cannot be true because "ret" is set to 1.

Fixes: 5785dd7a8ef0 ("drm/msm: Fix duplicate gpu node in icc summary")
