From d5f0b804368951b6b4a77d2f14b5bb6a04b0e011 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Sun, 7 Nov 2021 11:35:43 -0600 Subject: [PATCH] staging: r8188eu: Fix breakage introduced when 5G code was removed In commit 221abd4d478a ("staging: r8188eu: Remove no more necessary definitions and code"), two entries were removed from RTW_ChannelPlanMap[], but not replaced with zeros. The position within this table is important, thus the patch broke systems operating in regulatory domains osted later than entry 0x13 in the table. Unfortunately, the FCC entry comes before that point and most testers did not see this problem.
