Merge tag 'wireless-2024-09-04' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless
Kalle Valo says: ==================== wireless fixes for v6.11 Hopefully final fixes for v6.11 and this time only fixes to ath11k driver. We need to revert hibernation support due to reported regressions and we have a fix for kernel crash introduced in v6.11-rc1. * tag 'wireless-2024-09-04' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless: MAINTAINERS: wifi: cw1200: add net-cw1200.h Revert "wifi: ath11k: support hibernation" Revert "wifi: ath11k: restore country code during resume" wifi: ath11k: fix NULL pointer dereference in ath11k_mac_get_eirp_power() ==================== Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
