Subject: [PATCH v1] Bluetooth: btintel_pcie: Clear automask on spurious interrupts
Date: Tue, 25 Aug 2026 21:55:12 +0530 [thread overview]
Message-ID: <20260825162512.143965-1-kiran.k@intel.com> (raw)
On spurious interrupt where the TX and RX causes are not set, driver was
not clearing the auto mask which can block all the interrupts. Driver
needs to clear the automask even if no causes are set.
