commit 2397d61ee45cddb8f3bd3a3a9840ef0f0b5aa843 upstream.
This reverts commit 235b630eda072d7e7b102ab346d6b8a2c028a772.
This commit was found responsible for issues with SD card recognition, as users had to re-insert their cards in the readers and wait for a while. As for some people the SD card was involved in the boot process it also caused boot failures.
