From: Brian Norris <briannorris@xxxxxxxxxxxx> commit 1ec7ed5163c70a0d040150d2279f932c7e7c143f upstream. This reverts commit 2dc016599cfa9672a147528ca26d70c3654a5423. Users are reporting regressions in regulatory domain detection and channel availability. The problem this was trying to resolve was fixed in firmware anyway: QCA6174 hw3.0: sdio-4.4.1: add firmware.bin_WLAN.RMH.4.4.1-00042 https://github.com/kvalo/ath10k-firmware/commit/4d382787f0efa77dba40394e0bc604f8eff82552 Link: https://bbs.archlinux.org/viewtopic.php?id=254535 Link: http://lists.infradead.org/pipermail/ath10k/2020-April/014871.html Link: http://lists.infradead.org/pipermail/ath10k/2020-May/015152.html Link: https://lore.kernel.org/all/1c160dfb-6ccc-b4d6-76f6-4364e0adb6dd@xxxxxxx/ Fixes: 2dc016599cfa ("ath: add support for special 0x0 regulatory domain") Cc: <stable@xxxxxxxxxxxxxxx> Cc: Wen Gong <wgong@xxxxxxxxxxxxxx> Signed-off-by: Brian Norris <briannorris@xxxxxxxxxxxx> Signed-off-by: Kalle Valo <quic_kvalo@xxxxxxxxxxx> Link: https://lore.kernel.org/r/20200527165718.129307-1-briannorris@xxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/net/wireless/ath/regd.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) --- a/drivers/net/wireless/ath/regd.c +++ b/drivers/net/wireless/ath/regd.c @@ -667,14 +667,14 @@ ath_regd_init_wiphy(struct ath_regulator /* * Some users have reported their EEPROM programmed with - * 0x8000 or 0x0 set, this is not a supported regulatory - * domain but since we have more than one user with it we - * need a solution for them.
