mmc: core: warn when card doesn't support HPI

2012-03-27T16:20:12+00:00

Someone could use send_hpi_cmd() on a card that doesn't advertise support
for HPI.  Then maybe didn't work fine.  Because card->ext_csd.hpi_cmd
didn't set.  So if card didn't support hpi, return the warning message.

And CMD12's flags is MMC_RSP_R1B.

mmc: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:32:06+00:00

These two basic defines were everywhere, simply because module.h
was also everywhere.   But we are cleaning up the latter.  So make
the exporters actually call out their need for the include.

mmc: initialize struct mmc_request at declaration time

2011-05-25T01:02:01+00:00

Converts from:
	struct mmc_request mrq;
	memset(&mrq, 0, sizeof(struct mmc_request));

to:
	struct mmc_request mrq = {0};

because it's shorter, as performant, and easier to work out whether
initialization has happened.

mmc: core: Allow setting CMD timeout for CMD6 (SWITCH).

2011-05-25T01:01:13+00:00

CMD6 is an R1B-type command, where DAT is used as busy. Depending
on register written using CMD6, timeout value can be different
as per spec.
