From d38dcad4e7b48f3d68d5d058f8f4f52a99862e6e Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 20 Mar 2017 19:50:32 +0200 Subject: mmc: sdhci: Let drivers decide whether to use mmc_retune_needed() with pm Devices might save and restore tuning values so that re-tuning might not be needed after a pm transition. Let drivers decide by pushing the mmc_retune_needed() logic down to them.
