Subject: [PATCH AUTOSEL 5.15 07/17] can: kvaser_usb: fix return value for hif_usb_send_regout

From: Chen Ni <nichen@...as.ac.cn>

[ Upstream commit 0d34d8163fd87978a6abd792e2d8ad849f4c3d57 ]

As the potential failure of usb_submit_urb(), it should be better to
return the err variable to catch the error.
