Hello,

When I pull my SD card out of my laptop, I get the following:

tifm_7xx1: demand removing card from socket 3
=====================================
[ BUG: bad unlock balance detected! ]
-------------------------------------
tifm/0/1919 is trying to release lock (&fm->lock) at:
[<f90d392f>] tifm_7xx1_switch_media+0x2e9/0x326 [tifm_7xx1]
but there are no more locks to release!

other info that might help us debug this:
no locks held by tifm/0/1919.
