Subject: [PATCH] staging: r8188eu: avoid use of goto statement
Message-ID: <YXY5jtR6neQ+ad+C@Sauravs-MacBook-Air.local>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

Precedence: bulk

Remove the goto statement from _rtw_init_cmd_priv(). In this function
goto statement can be replace by return statement. By replacing the
goto statement with return statement local variable "res" is also
not required.As on goto label exit, function only return it is not
performing any cleanup.Avoiding goto will simplify the function.
