arm_smmu_install_ste_for_dev cannot fail and always returns 0, however the fact that it returns int means that callers end up implementing redundant error handling code which complicates STE tracking and is never executed. This patch changes the return type of arm_smmu_install_ste_for_dev to void, to make it explicit that it cannot fail. Signed-off-by: Will Deacon <will.deacon@arm.com>
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.
