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.
