Subject: [PATCH] USB: storage: ums-realtek: fix error code in rts51x_read_mem()
Date: Fri, 4 Mar 2022 10:35:04 +0300 [thread overview]
Message-ID: <20220304073504.GA26464@kili> (raw)
The rts51x_read_mem() function should return negative error codes.
Currently if the kmalloc() fails it returns USB_STOR_TRANSPORT_ERROR (3)
which is treated as success by the callers.
Fixes: 065e60964e29 ("ums_realtek: do not use stack memory for DMA")
