[PATCH v3] ASoC: use DEFINE_SHOW_ATTRIBUTE() to decrease code duplication

[Donglin Peng]

There is some duplicate code in soc-core.c, and the kernel provides
DEFINE_SHOW_ATTRIBUTE() helper macro to decrease it in seq_file.h.

Your patch has been corrupted somewhere (probably in your mail client) -
there's word wrapping here.

Hi Mark, do you know the way to disable gmail word wrap in plain text mode?
I find that gmail will force to wrap word at 70 characters in plain text mode.

There is a connection error when I use git send-email to send the patch
because I am using VPN.

You may use SMTPS port (587 IIRC?) of Gmail to send a patch via git send-email.
