From 26711cc7e0641781e696c775fa84f7415ff49b4e Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Thu, 16 Jan 2020 16:21:50 +0530 Subject: [PATCH] mmc: sdhci: Refactor sdhci_set_timeout() [ Upstream commit 7d76ed77cfbd39468ae58d419f537d35ca892d83 ] Refactor sdhci_set_timeout() such that platform drivers can do some functionality in a set_timeout() callback and then call __sdhci_set_timeout() to complete the operation.
