+void ufshpb_init(struct ufs_hba *hba)
+{
+        struct ufshpb_dev_info *hpb_dev_info = &hba->ufshpb_dev;
+        int try;
+        int ret;

+        if (!ufshpb_is_allowed(hba))
+                return;

Here it is better to check "dev_info->hpb_enable", if HPB is not
enabled from UFS device level,  doesn't need to create mempool and take
other memory resource.

I will add checking dev_info->hpb_enable value.
if (!ufshpb_is_allowed(hba) || !dev_info->hpb_enable)
