Subject: drm/radeon: no need to check all relocs for duplicates
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16557f1ef0e14fd43b0a46b7dc89c431020ff3e2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/radeon: no need to check all relocs for duplicates

Only check the previously checked relocs for
duplicates. Also leaving the handle uninitialized
isn't such a good idea.
