Revert "mmc: core: wait while adding MMC host to ensure root mounts successfully" This reverts commit 3500ed90b26a9935b943b5e2e4cd3226600d6b58. The reverted patch caused a significant performance regression when booting with the root file system on eMMC. Before the patch: [ 1.625623] VFS: Mounted root (ext4 filesystem) readonly on device 179:2. After the patch: [ 1.935851] VFS: Mounted root (ext4 filesystem) readonly on device 179:2. That was an addition of 310 ms which is a 19% performance degradation. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>
