Stefan Schmidt says: ==================== pull-request: ieee802154 for net 2024-09-27 Jinjie Ruan added the use of IRQF_NO_AUTOEN in the mcr20a driver and fixed and addiotinal build dependency problem while doing so. Jiawei Ye, ensured a correct RCU handling in mac802154_scan_worker. * tag 'ieee802154-for-net-2024-09-27' of git://git.kernel.org/pub/scm/linux/kernel/git/wpan/wpan: net: ieee802154: mcr20a: Use IRQF_NO_AUTOEN flag in request_irq() mac802154: Fix potential RCU dereference issue in mac802154_scan_worker ieee802154: Fix build error ==================== Link: https://patch.msgid.link/20240927094351.3865511-1-stefan@datenfreihafen.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
