From d7fb9c24209556478e65211d7a1f056f2d43cceb Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Tue, 26 Jan 2021 10:43:13 +0100 Subject: [PATCH] mmc: sdhci-pltfm: Fix linking err for sdhci-brcmstb The implementation of sdhci_pltfm_suspend() is only available when CONFIG_PM_SLEEP is set, which triggers a linking error: "undefined symbol: sdhci_pltfm_suspend" when building sdhci-brcmstb.c. Fix this by implementing the missing stubs when CONFIG_PM_SLEEP is unset.
