X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4aa896c4baaab2b4f499c7434f85457f9f3d9fe4;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ip_gre: remove an extra dst_release()

commit 68c331631143 (v4 GRE: Add TCP segmentation offload for GRE)
introduced a bug in error path.

dst is attached to skb, so will be released when skb is freed.
