Subject: [IPV4]: Remove unnecessary check for opt->is_data in ip_options_compile.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10fe7d85e2e4042f703a10bed4123f2105eadad2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[IPV4]: Remove unnecessary check for opt->is_data in ip_options_compile.

There is the only way to reach ip_options compile with opt != NULL:

ip_options_get_finish
    opt->is_data = 1;
    ip_options_compile(opt, NULL)

So, checking for is_data inside opt != NULL branch is not needed.
