Subject: [GIT PULL] SCSI fixes for 6.18-rc2
All driver fixes. The big change is the storvsc one to rejig the
hyper-v channel handling to be more efficient for SMP virtual machines.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Alok Tiwari (1):
scsi: qla4xxx: Fix typos in comments
Dan Carpenter (1):
scsi: libfc: Prevent integer overflow in fc_fcp_recv_data()
Jingyi Wang (1):
scsi: ufs: phy: dt-bindings: Add QMP UFS PHY compatible for Kaanapali
Long Li (1):
scsi: storvsc: Prefer returning channel with the same CPU as on the I/O issuing CPU
Nitin Rawat (1):
scsi: ufs: qcom: dt-bindings: Document the Kaanapali UFS controller
