6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geoffrey D. Bennett <g@xxxxx>
[ Upstream commit ca459dfa7d4ed9098fcf13e410963be6ae9b6bf3 ]
scarlett2_usb_set_config() calls scarlett2_usb_get() but was not
checking the result. Return the error if it fails rather than
continuing with an invalid value.
