From ba6df3ea68196d54a1e8299cea1bf4565fc755c5 Mon Sep 17 00:00:00 2001 From: Lin Ma Date: Thu, 7 Apr 2022 10:21:10 +0800 Subject: usb-storage: isd200: fix initFunction error return The initFunction is called when probing a new device, its call relation is like: USB core: probe() -> usb_stor_probe2() -> usb_stor_acquire_resources() -> isd200_init_info() That is, the error return of the initFunction should tell USB core what happened instead of using custom error code like ISD200_ERROR.
