Hello Sylwester Nawrocki,
This is a semi-automatic email about new static checker warnings.
The patch fa91f1056f17: "[media] exynos4-is: Add support for
asynchronous subdevices registration" from Feb 24, 2014, leads to the
following Smatch complaint:
drivers/media/platform/exynos4-is/media-dev.c:1206 __fimc_md_set_camclk()
warn: variable dereferenced before check 'fmd' (see line 1203)
drivers/media/platform/exynos4-is/media-dev.c
1202 */
1203 if (fmd->pdev->dev.of_node)
^^^^^^^^^
Patch adds a dereference.
1204 return 0;
1205
1206 if (WARN_ON(si->clk_id >= FIMC_MAX_CAMCLKS) || !fmd || !fmd->pmf)
^^^^
Old check.
1207 return -EINVAL;
1208
regards,
dan carpenter
