The mutex lock is not used at all, remove it.
The *vmmc_regulator is not necessary, use a local variable in
stw481x_vmmc_regulator_probe() instead.

Hi Lee,
I thought you will pick up this patch.
But now I got your ack, I'm not sure what should I do now.
Should I resend the patch?

Regards,
Axel

I think Mark should pick this up, as the only changes in MFD are in
the header.
