Don't cast away the __iomem from the io_mapping functions so that sparse won't be so unhappy when we pass the pointer to the unmap functions. Instead let's move the cast to where we actually use the pointer. Fixes the following sparse warnings: i915_gem.c:1022:33: warning: incorrect type in argument 1 (different address spaces) i915_gem.c:1022:33: expected void [noderef] <asn:2>*vaddr i915_gem.c:1022:33: got void *[assigned] vaddr i915_gem.c:1027:34: warning: incorrect type in argument 1 (different address spaces) i915_gem.c:1027:34: expected void [noderef] <asn:2>*vaddr i915_gem.c:1027:34: got void *[assigned] vaddr i915_gem.c:1199:33: warning: incorrect type in argument 1 (different address spaces) i915_gem.c:1199:33: expected void [noderef] <asn:2>*vaddr i915_gem.c:1199:33: got void *[assigned] vaddr i915_gem.c:1204:34: warning: incorrect type in argument 1 (different address spaces) i915_gem.c:1204:34: expected void [noderef] <asn:2>*vaddr i915_gem.c:1204:34: got void *[assigned] vaddr Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170901171252.31025-2-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
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.
