If you want to make it real patch, please convert it to follow IWYU.
What you are saying is basically comes from kernel.h (yeah, i2c.h happens
earlier, but the kernel.h is PITA currently).

WRT to the kmalloc() use, wouldn't it be simply better to use
i2c_master_send_dmasafe() and kill that kmalloc() dance in the driver?
