Subject: 答复: 答复: 答复: [PATCH 1/1] sound: Fix compile error of seq_device.c

Oh, I get it.

I met the compile error when compile the kernel 3.10 on CentOS7 and fix it, then I find the seq_device of upstream is same.
So I thought it should be fixed.

OK. Let me compile the upstream codes on CentOS7 again.

Does this happen with the latest upstream kernel code at all...?
