Subject: [PATCH 5.17 0587/1126] scsi: pm8001: Fix payload initialization in pm80xx_encrypt_update()

From: Damien Le Moal <damien.lemoal@...nsource.wdc.com>

[ Upstream commit f8b12dfb476dad38ce755aaf5e2df46f06f1822e ]

All fields of the kek_mgmt_req structure have the type __le32. So make sure
to use cpu_to_le32() to initialize them. This suppresses the sparse
warning:

warning: incorrect type in assignment (different base types)
   expected restricted __le32 [addressable] [assigned] [usertype] new_curidx_ksop
   got int
