The power management handling in dw_i2c_plat_probe() is somewhat messy and it is rather hard to figure out the code intention for the case when pm_disabled is set. In that case, the driver doesn't enable runtime PM at all, but in addition to that it calls pm_runtime_forbid() as though it wasn't sure if runtime PM might be enabled for the device later by someone else. Although that concern doesn't seem to be actually valid, the device is clearly still expected to be PM-capable even in the pm_disabled set case, so a better approach would be to enable runtime PM for it unconditionally and prevent it from being runtime-suspended by using pm_runtime_get_noresume(). Make the driver do that. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de> |

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.
