    Subject[PATCH AUTOSEL 5.4 017/130] staging: rtl8192u: fix wrong judgement in rtl8192_rx_isr
    Date
    From: Zhang Qilong <zhangqilong3@huawei.com>

    [ Upstream commit 071dc1787a2f8bb636f864c1f306280deea3b1d5 ]

    The 'EPERM' cannot appear in the previous path, we
    should use '-EPERM' to check it. For example:

    Call trace:
    ->rtl8192_rx_isr
    ->usb_submit_urb
    ->usb_hcd_submit_urb
    ->rh_urb_enqueue
    ->rh_queue_status
    ->usb_hcd_link_urb_to_ep
