Subject: [PATCH 02/13] staging: r8188eu: process HalUsbSetQueuePipeMapping8188EUsb's return value
Date:   Sat,  6 Aug 2022 21:55:29 +0200
Message-Id: <20220806195540.777390-3-martin@kaiser.cx>

At the moment, HalUsbSetQueuePipeMapping8188EUsb returns an error status
to rtl8188eu_interface_configure, where this status is discarded.

Pass the error status from rtl8188eu_interface_configure to
rtw_usb_if1_init and handle it there.
