From f2943046881daca68808d542aa6312c4b4d899af Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Thu, 5 Jun 2025 13:14:16 +0200 Subject: [PATCH] wifi: mt76: Assume __mt76_connac_mcu_alloc_sta_req runs in atomic context Rely on GFP_ATOMIC flag in __mt76_connac_mcu_alloc_sta_req since it can run in atomic context. This is a preliminary patch to fix a 'sleep while atomic' issue in mt7996_mac_sta_rc_work().
