Subject: ftrace: remove unnecessary if condition of __unregister_ftrace_function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b3535c6390f27d04273e4eee0bc687f171fbf5f4;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ftrace: remove unnecessary if condition of __unregister_ftrace_function

Because it has goto out before ftrace_list == &ftrace_list_end,
that's to say, we never meet this condition.
