From 5c67aa59bd8f99d70c81b5e71bd02083056a8486 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 14 Oct 2021 16:26:11 +0300 Subject: [PATCH] mmc: sdhci-pci: Remove dead code (struct sdhci_pci_data et al) The last user of this struct gone a couple of releases ago. Besides that there were not so many users of this API for more than 10 years: 1/ The one is Intel Merrifield, that had been added 2016-08-31 by the commit 3976b0380b31 ("x86/platform/intel-mid: Enable SD card detection on Merrifield") and removed 2021-02-11 by the commit 4590d98f5a4f ("sfi: Remove framework for deprecated firmware"). 2/ The other is Intel Sunrisepoint related, that had been added 2015-02-06 by the commit e1bfad6d936d ("mmc: sdhci-pci: Add support for drive strength selection for SPT") and removed 2017-03-20 by the commit 51ced59cc02e ("mmc: sdhci-pci: Use ACPI DSM to get driver strength for some Intel devices"). Effectively this is a revert of the commit 52c506f0bc72 ("mmc: sdhci-pci: add platform data").
