sysfs attributes preferably should not be manually be registered but instead the driver.groups / driver.dev_groups driver struct members should be used to have the driver core handle this in a race free manner. Using driver.groups would be the most direct replacement for driver_[add|remove]_file, but some of the attributes actually need access to the struct atomisp_device (*), so as part of modernizing this part of the atomisp driver this change also makes the sysfs attribute device attributes instead of driver attributes. *) Before this change accessing these attributes without the driver having bound would result in a NULL pointer deref, this commit fixes this.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
