Synchronize the ath11k backports with the current ath-next tree. All of the changes are various bugfixes, there is no new major feature. Notable bugfixes are: * WCN6855 board name fixes * One MSI vector booting is working again This is rather important for most of the older platforms. * DFS CAC state in virtual interfaces was fixed * TX power during CAC reporting Signed-off-by: Robert Marko <robimarko@gmail.com>

|
|
|
Use 'kstrtoul_from_user()' in 'ath11k_write_file_spectral_count()'
|
|
and 'ath11k_write_file_spectral_bins()'
