Subject: USB: usb-storage fails to attach to Huawei Datacard cdrom device
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d0defb855c8504c49b92bdc0203689ce9b4cf7ba;p=deliverable%2Flinux.git

USB: usb-storage fails to attach to Huawei Datacard cdrom device

In this patch, we always make the return value of function
usb_stor_huawei_e220_init to be zero. Then it will not prevent usb-storage
driver from attaching to the CDROM device of Huawei Datacard.
