Use ufshcd_is_wb_allowed() directly instead of ufshcd_wb_sup() since ufshcd_wb_sup() just returns the result of ufshcd_is_wb_allowed(). 2. In ufshcd_suspend(), "else if (!ufshcd_is_runtime_pm(pm_op)) can be simplified to "else" since both have the same meaning. This patch does not change any functionality.
