To: gregkh@...uxfoundation.org, linux-kernel@...r.kernel.org,

Subject: [PATCH v2] fix code style in socklnd_proto.c
fix coding style by ./scripts/checkpatch.pl.
fix 80 charracters limit, space prohibited between function name and
open parenthesis '('
and braces {} are not necessary for single statement blocks.
Before patch is html format. But this is plain text format.
Before patch is From: line didn't match the Signed-off-by line. Align
the these lines.
