[PATCH][next] misc: hisi_hikey_usb: fix return of uninitialized ret status variable

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently the return value from ret is uninitialized so the function
hisi_hikey_usb_parse_kirin970 is returning a garbage value when
succeeding. Since ret is not used anywhere else in the function, remove
it and just return 0 success at the end of the function.

Addresses-Coverity: ("Uninitialixed scalar variable")
Fixes: d210a0023590 ("misc: hisi_hikey_usb: add support for Hikey 970")
