gcc says:
drivers/i2c/muxes/i2c-mux-reg.c:182:15: warning: variable 'initial_state' set but not used [-Wunused-but-set-variable]
It seens you prepared for setting the initial state but don't do the

coccicheck says:
drivers/i2c/muxes/i2c-mux-reg.c:288:3-8: No need to set .owner here. The core will do it.
