Subject: Remove unnecessary reset in usb_stor_get_info
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=56887e27aee57db866a877e60a9141caa32d4636;p=u-boot.git

Remove unnecessary reset in usb_stor_get_info

The reset request in usb_stor_get_info is causing issues with some usb
sticks. Some of these sticks vendor_id/product_id have been hardcoded to
not reset but better is to remove the reset altogether. It is not needed.
