Subject: rpc_pipe: remove the clntXX dir if creating the pipe fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3396f92f8be606ea485b0a82d4e7749a448b013b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

rpc_pipe: remove the clntXX dir if creating the pipe fails

In the event that we create the gssd/clntXX dir, but the pipe creation
subsequently fails, then we should remove the clntXX dir before
returning.
