Subject: dccp: consistently use dccp_write_space()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e2f6dd298beb93c30e1699a5c26492a10214447;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dccp: consistently use dccp_write_space()

DCCP uses dccp_write_space() for sk->sk_write_space method.

Unfortunately a passive connection (as provided by accept())
is using the generic sk_stream_write_space() function.

Lets simply inherit sk->sk_write_space from the parent
instead of forcing the generic one.
