Subject: SUNRPC: Remove resource leak in svc_rdma_send_error()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5e502681007779d4762fb3ef7e80a3ecd1cfe6b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

SUNRPC: Remove resource leak in svc_rdma_send_error()

We leak the memory allocated to 'ctxt' when we return after
'ib_dma_mapping_error()' returns !=0.
