[ Upstream commit da79bf41a4d170ca93cc8f3881a70d734a071c37 ] The call to of_get_child_by_name returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: drivers/media/platform/exynos4-is/fimc-is.c:813:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 807, but without a corresponding object release within this function. drivers/media/platform/exynos4-is/fimc-is.c:870:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 807, but without a corresponding object release within this function. drivers/media/platform/exynos4-is/fimc-is.c:885:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 807, but without a corresponding object release within this function. drivers/media/platform/exynos4-is/media-dev.c:545:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 541, but without a corresponding object release within this function. drivers/media/platform/exynos4-is/media-dev.c:528:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 499, but without a corresponding object release within this function. drivers/media/platform/exynos4-is/media-dev.c:534:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 499, but without a corresponding object release within this function.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
