This patch changes the calls to uclass_first/next_device() in blk_first/ next_device() to use uclass_find_first/next_device() instead. These functions don't prepare the devices, which is correct in this case.
With this patch applied, the "usb storage" command now works again as expected: => usb storage Device 0: Vendor: SanDisk Rev: 1.00 Prod: Ultra Type: Removable Hard Disk Capacity: 58656.0 MB = 57.2 GB (120127488 x 512) Without this patch, it used to generate this buggy output: => usb storage Card did not respond to voltage select! mmc_init: -95, time 26 No storage devices, perhaps not 'usb start'ed..?
