pr_* macros replaced with dev_* as they are more preffered over pr_*. each file which had pr_* was reviewed manually and replaced with dev_*. here we have actually used the various snd_card which was added to some structures of ctxfi via a previous patch of this series. in the ctvmem.c file we have passed a reference of ct_atc as an argument to get_vm_block function so that it can be used from dev_*. since dev_* will print the device information , so the prefix of "ctxfi" from the various pr_* were also removed.
