This adds a defined-but-not-used warning.  The MMC tree doesn't
currently generate any warnings, so it would be good to avoid adding new
ones, though I understand why it might make sense in this case.

drivers/mmc/core/quirks.c:30:13: warning: âadd_quirkâ defined but not used
drivers/mmc/core/quirks.c:38:13: warning: âremove_quirk_hookâ defined but not used

This doesn't compile, missing a comma.  Was it tested?

drivers/mmc/core/quirks.c:63:2: error: expected â}â before â{â token

(Otherwise, looks good.)
