5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Egorenkov <egorenar@xxxxxxxxxxxxx>
[ Upstream commit 9c922b73acaf39f867668d9cbe5dc69c23511f84 ]
Use correct symbolic constants IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN
to initialize nvme reipl block when 'scp_data' sysfs attribute is
being updated. This bug had not been detected before because
the corresponding fcp and nvme symbolic constants are equal.
Fixes: 23a457b8d57d ("s390: nvme reipl")
