Subject: re: drm/mediatek: Add DPI sub driver
Date: Thu, 12 May 2016 13:26:23 +0300 [thread overview]
Message-ID: <20160512102622.GA14068@mwanda> (raw)
Hello Jie Qiu,
This is a semi-automatic email about new static checker warnings.
The patch 9e629c17aa8d: "drm/mediatek: Add DPI sub driver" from Jan
4, 2016, leads to the following Smatch complaint:
drivers/gpu/drm/mediatek/mtk_dpi.c:436 mtk_dpi_set_display_mode()
error: we previously assumed 'dpi' could be null (see line 435)
drivers/gpu/drm/mediatek/mtk_dpi.c
434
435 if (!dpi) {
^^^^
Check.
436 dev_err(dpi->dev, "invalid argument\n");
^^^^^^^^^
Deref. Can dpi even be NULL, btw?
437 return -EINVAL;
438 }
regards,
dan carpenter
