Subject: rtlwifi: rtl8192ce: Fix editing error that causes silent memory corruption
From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>
commit 99a82f734aa6c6d397e029e6dfa933f04e0fa8c8 upstream.
In the major update of the rtlwifi-family of drivers, there was an editing
mistake. Unfortunately, this particular error leads to memory corruption that
silently leads to failure of the system. This patch is one of three needed to
fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951.
