The patch titled
sdhci-of: rename main driver file prior to reorganization
has been removed from the -mm tree. Its filename was
sdhci-of-rename-main-driver-file-prior-to-reorganization.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: sdhci-of: rename main driver file prior to reorganization
From: Albert Herranz <albert_herranz@xxxxxxxx>
This patch renames sdhci-of.c to sdhci-of-core.c before reorganizing the
driver to support additional hardware.
The driver is still built as sdhci-of despite the rename of the file. No
functional change.
