    i4l: kill big kernel lock · 72250d44
    Arnd Bergmann authored
    The isdn4linux driver uses the big kernel lock only
    to serialize access to a few fields in its own
    modem_info structure.
    The easiest replacement is a driver-wide mutex.
    More fine-grained locking would be more appropriate
    here, but likely harder to implement.
