For older versions of gcc, the array = {0}; will cause warnings:
drivers/scsi/ufs/ufshcd-crypto.c: In function 'ufshcd_crypto_keyslot_program':
drivers/scsi/ufs/ufshcd-crypto.c:62:8: warning: missing braces around initializer [-Wmissing-braces]
union ufs_crypto_cfg_entry cfg = { 0 };
^
drivers/scsi/ufs/ufshcd-crypto.c:62:8: warning: (near initialization for 'cfg.reg_val') [-Wmissing-braces]
drivers/scsi/ufs/ufshcd-crypto.c: In function 'ufshcd_clear_keyslot':
drivers/scsi/ufs/ufshcd-crypto.c:103:8: warning: missing braces around initializer [-Wmissing-braces]
union ufs_crypto_cfg_entry cfg = { 0 };
^
2 warnings generated
Fixes: 70297a8ac7a7 ("scsi: ufs: UFS crypto API")
