In the Linux kernel, the following vulnerability has been resolved:

i2c: smbus: fix NULL function pointer dereference

Baruch reported an OOPS when using the designware controller as target
only. Target-only modes break the assumption of one transfer function
always being available. Fix this by always checking the pointer in
__i2c_transfer.

[wsa: dropped the simplification in core-smbus to avoid theoretical regressions]
