Subject: mmc: atmel-mci: Remove redundant suspend and resume callbacks
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=914af7c2e58f49c3f5940030cfc30c6693069934;p=deliverable%2Flinux.git

mmc: atmel-mci: Remove redundant suspend and resume callbacks

Suspend and resume of cards are handled by the protocol layer and
consequently the mmc_suspend|resume_host APIs are marked as deprecated.

While moving away from using the deprecated APIs, there are nothing
left to be done for the suspend and resume callbacks, so remove them.
