[PATCH 10/15] pcmcia: do not lock socket driver module in pcmcia_get_socket()

[Dominik Brodowski]

Do not lock the socket driver module in pcmcia_get_socket(), as
the PCMCIA core can handle a socket module removal: In
pcmcia_unregister_socket(), we explicitely wait for the last
put_device() to succeed.
