`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.
