This series contains two changes and it is based on 5.11/scsi-queue The 1st change is just a minor fix. The 2nd change is to synchronize user layer access through UFS sysfs nodes, so that system PM ops (suspend, resume and shutdown), error handling and async probe won't be disturbed by user layer access. Can Guo (2): scsi: ufs: Fix a possible NULL pointer issue scsi: ufs: Protect PM ops and err_handler from user access through sysfs drivers/scsi/ufs/ufs-sysfs.c | 104 ++++++++++++++++++++++++++++++++++++------- drivers/scsi/ufs/ufshcd.c | 49 ++++++++++++-------- drivers/scsi/ufs/ufshcd.h | 5 ++- 3 files changed, 123 insertions(+), 35 deletions(-)
