From 5704974eb30050cd1758b5ab280d04cb56651596 Mon Sep 17 00:00:00 2001 From: Aditya Pakki Date: Sun, 15 Dec 2019 13:58:58 -0600 Subject: [PATCH] orinoco: avoid assertion in case of NULL pointer [ 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.
