From: GuoHan Zhao Date: Mon, 27 Apr 2026 01:21:28 +0000 (+0800) Subject: vfio/xe: avoid duplicate reset in xe_vfio_pci_reset_done X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9285405c5f6144f4444f97bf3048d865e11cc1d;p=thirdparty%2Flinux.git vfio/xe: avoid duplicate reset in xe_vfio_pci_reset_done xe_vfio_pci_reset_done() sets deferred_reset and, when it manages to acquire state_mutex itself, hands the cleanup off to xe_vfio_pci_state_mutex_unlock(). That helper already clears deferred_reset and runs xe_vfio_pci_reset() before dropping the mutex. Calling xe_vfio_pci_reset() again right afterwards repeats the reset handling unnecessarily.
