Merge tag 'driver-core-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here's the big driver-core pull request for 3.17-rc1. Largest thing in here is the dma-buf rework and fence code, that touched many different subsystems so it was agreed it should go through this tree to handle merge issues. There's also some firmware loading updates, as well as tests added, and a few other tiny changes, the changelog has the details. All have been in linux-next for a long time" * tag 'driver-core-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (32 commits) ARM: imx: Remove references to platform_bus in mxc code firmware loader: Fix _request_firmware_load() return val for fw load abort platform: Remove most references to platform_bus device test: add firmware_class loader test doc: fix minor typos in firmware_class README staging: android: Cleanup style issues Documentation: devres: Sort managed interfaces Documentation: devres: Add devm_kmalloc() et al fs: debugfs: remove trailing whitespace kernfs: kernel-doc warning fix debugfs: Fix corrupted loop in debugfs_remove_recursive stable_kernel_rules: Add pointer to netdev-FAQ for network patches driver core: platform: add device binding path 'driver_override' driver core/platform: remove unused implicit padding in platform_object firmware loader: inform direct failure when udev loader is disabled firmware: replace ALIGN(PAGE_SIZE) by PAGE_ALIGN firmware: read firmware size using i_size_read() firmware loader: allow disabling of udev as firmware loader reservation: add suppport for read-only access using rcu reservation: update api and add some helpers ...

150 * Takes all necessary steps to ioremap a mem resource. Uses managed device, so
151 * everything is undone on driver detach. Checks arguments, so you can feed
152 * it the result from e.g. platform_get_resource() directly. Returns the
153 * remapped pointer or NULL on error. Usage example:
154 *
155 * res = platform_get_resource(pdev, IORESOURCE_MEM, 0);
156 * base = devm_request_and_ioremap(&pdev->dev, res);
157 * if (!base)
