Subject: usb: storage: Show number of storage devices detected for DM_USB
X-Git-Tag: v2017.03-rc1~97^2~5
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=b984700ca4b98597825fbc79c47e7a621889adaf;p=u-boot

usb: storage: Show number of storage devices detected for DM_USB

By enabling DM_USB information about number of storage devices
was lost.
Get this information back simply by printing number of devices detected
via BLK uclass.

For example:
scanning bus 0 for devices... 7 USB Device(s) found
       scanning usb for storage devices... 3 Storage Device(s) found
       scanning usb for ethernet devices... 0 Ethernet Device(s) found
