[PATCH] fix crash in yenta_bh() on card insertion/removal

In the current kernels, when a PCMCIA card is inserted into or
removed from a socket, the kernel oopses because yenta_bh() tries to
dereference a NULL pointer.

The attached patch initialises the argument to yenta_bh() so that this
doesn't happen.
