Subject: [PATCH] USB: mos7840: fix pointer casts

commit 683a0e4d7971c3186dc4d429027debfe309129aa upstream.

Silence compiler warnings on 64-bit systems introduced by commit
05cf0dec ("USB: mos7840: fix race in led handling") which uses the
usb-serial data pointer to temporarily store the device type during
probe but failed to add the required casts.

[gregkh - change uintptr_t to unsigned long]
