Hi Mark,

This isn't needed for 2.6.39.

This compile error is actually caused by my fault, see below commit.

commit 0ed625b2f2751c249417bd28694e37ef48eb5fbb
Author: Lu Guanqun <guanqun.lu at intel.com>

    sst: make register_sst_card more self-contained
    
    register_sst_card is used in ASoC code with field `scard_ops` being NULL.
    Without this patch, there will be NULL dereference.

And this commit is only in your branch for-2.6.40. I failed to add
CONFIG_INTELMID=y in my previous test, so this error is hidden.
