[PATCH 4/4] mmc: Add mmc_host_<level> logging

Joe Perches joe at perches.com
Tue Nov 15 18:32:08 EST 2011


Centralize the pr_<level> uses of mmc_hostname into specific
mmc_host_<level> calls to allow a flexible presentation style
and shorten the code a bit.

Add mmc_host_<level> macros.
Convert the logging calls from:
	pr_<level>("%s: ...", mmc_hostname(foo)
to:
	mmc_host_<level>(foo, ...)

Add a couple of missing newlines.
Convert bare printks to pr_cont where appropriate.
Spelling/typo fix of initialiazed to initialized.
