Subject: [PATCH 4.19 130/338] scsi: pm8001: Fix command initialization in pm8001_chip_ssp_tm_req()

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

[ Upstream commit cd2268a180117aa8ebb23e090ba204324b2d0e93 ]

The ds_ads_m field of struct ssp_ini_tm_start_req has the type __le32.
Assigning a value to it should thus use cpu_to_le32(). This fixes the
sparse warning:

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