[PATCH AUTOSEL 4.4 048/100] orinoco: avoid assertion in case of NULL pointer

[Sasha Levin]

From: Aditya Pakki <pakki001@xxxxxxx>

[ Upstream commit c705f9fc6a1736dcf6ec01f8206707c108dca824 ]

In ezusb_init, if upriv is NULL, the code crashes. However, the caller
in ezusb_probe can handle the error and print the failure message.
The patch replaces the BUG_ON call to error return.
