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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Applied.
