Subject: [PATCH] staging: rtl8723bs: Fix uninitialized variable
Date: Sun, 6 Jun 2021 00:00:21 -0700 [thread overview]
Message-ID: <20210606070021.116284-1-wlooi@ucalgary.ca> (raw)
Uninitialized struct with invalid pointer causes BUG and prevents access
point from working. Access point works once I apply this patch.
https://forum.armbian.com/topic/14727-wifi-ap-kernel-bug-in-kernel-5444/
has more details.
