From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Found using coccicheck script under review at: https://lore.kernel.org/lkml/20210427141946.2478411-1-Julia.Lawall@xxxxxxxx/ As pm_runtime_resume_and_get() returns <= 0 take advantage of that to change the error checking to if (ret) which is more in keeping with the rest of this driver. This is a prequel to taking a closer look at the runtime pm in IIO drivers in general.
