Subject: mmc: davinci_mmc: Move away from using deprecated APIs
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5ffdeea522c8349ac96a11ec8e19486354fda808;p=deliverable%2Flinux.git

mmc: davinci_mmc: Move away from using deprecated APIs

Suspend and resume of cards are being handled from the protocol layer
and consequently the mmc_suspend|resume_host APIs are deprecated.

This means we can simplify the suspend|resume callbacks by removing the
use of the deprecated APIs.
