From: Masahiro Yamada Date: Wed, 23 Aug 2017 04:15:03 +0000 (+0900) Subject: mmc: sdhci-pltfm: export sdhci_pltfm_suspend/resume X-Git-Tag: v4.14-rc1~116^2~23 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=83a7b32ac66d863bfbd7bfdbf29dd61db72193de;p=linux.git mmc: sdhci-pltfm: export sdhci_pltfm_suspend/resume This will be useful when drivers want to reuse either suspend or resume callback instead of whole of sdhci_pltfm_pmops.
