Nothing... dev_* should be used when possible.

Actually all of the messages look like they are just plain noise and should
be removed.  Especially the ones in dt3155_{init,exit}_module.  A lot of the
ones in dt3155_probe look like noise also.

The ones in {read,write,wait}_i2c_reg just look messy.  Those functions also
don't have a device pointer to use the dev_* functions.

The ones in dt3155_irq_handler seem troublesome.  Isn't it a bad idea to output
a kernel message in an interrupt handler?

dt3155_{open,close} also look like noise.  Same with dt3155_init_board.

Maybe I should just submit a patch removing all of them?

Regards,
Hartley
