I reviewed and tested these patches:

c1ef4a2 [media] rtl2832: regmap is aware of lockdep, drop local locking hack
6636178 [media] rtl2832_sdr: get rid of empty regmap wrappers
001ad6b [media] rtl2832: declare that the i2c gate is self-locked
e2e82e4 [media] si2168: declare that the i2c gate is self-locked
b52f766 [media] si2168: convert to use an explicit i2c mux core
4ba9115 [media] rtl2832: convert to use an explicit i2c mux core
3f1778b [media] rtl2830: convert to use an explicit i2c mux core
5c8bfc8 [media] m88ds3103: convert to use an explicit i2c mux core
