since the split of host+gadget mode in commit 74c2e936 ("usb: musb: factor out hcd initalization") we leak the usb_hcd struct. We call now musb_host_cleanup() which does basically usb_remove_hcd() and also sets the hcd variable to NULL. Doing so makes the finall call to musb_host_free() basically a nop and the usb_hcd remains around for ever without anowner. This patch drops that NULL assignment for that reason.

This makes us sure that all requests are completed before we unbind gadget. There are assumptions in gadget API that all requests have to be completed and leak of complete can break some usb function drivers. For example unbind of ECM function can cause NULL pointer dereference: [ 26.396595] configfs-gadget gadget: unbind function 'cdc_ethernet'/e79c4c00 [ 26.414999] Unable to handle kernel NULL pointer dereference at virtual address 00000000 (...)

Commit 82c02f58 ("usb: musb: Allow multiple glue layers to be built in") enabled selecting multiple glue layers, which in turn exposed things more for randconfig builds. If NOP_USB_XCEIV is built-in and TUSB6010 is a loadable module, we will get: drivers/built-in.o: In function `tusb_remove': tusb6010.c:(.text+0x16a817): undefined reference to `usb_phy_generic_unregister' drivers/built-in.o: In function `tusb_probe': tusb6010.c:(.text+0x16b24e): undefined reference to `usb_phy_generic_register' make: *** [vmlinux] Error 1 Let's fix this the same way as commit 70c1ff4b ("usb: musb: tusb-dma can't be built-in if tusb is not"). And while at it, let's not allow selecting the glue layers except on platforms really using them unless COMPILE_TEST is specified: - TUSB6010 is in practise only used on omaps - DSPS is only used on TI platforms - UX500 is only used on STE platforms Cc: Linus Walleij <linus.walleij@linaro.org> Reported-by: Jim Davis <jim.epost@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

!strncmp(buf, "force host", 9) is true if and only if buf starts with "force hos". This was obviously not what was intended. The same error exists for "force full-speed", "force high-speed" and "test packet". Using strstarts avoids the error-prone hardcoding of the prefix length. For consistency, also change the other occurences of the !strncmp idiom. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Felipe Balbi <balbi@ti.com>

commit cc92f681 (usb: musb: Populate new IO functions for blackfin) added a typo which prevented MUSB's blackfin glue layer from being built. Due to lack of tests and compilers for that architecture, the typo ended up being merged and causing a build regression.

Blackfin's MUSB implementation lacks a bunch of registers which they end up not defining a macro for. In order to avoid build breaks, let's ifdef out some of the registers from our regdump debugfs utility so that we don't try to use those on Blackfin builds.

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger: "kernel: Provide READ_ONCE and ASSIGN_ONCE As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses. Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types.

strcmp was lost when all other string functions were removed, but we still have an optimized version for this on CRISv32, so any driver built as a module would not have access to this symbol. In a similar manner, we had optimized versions of csum_partial_copy_from_user and __do_clear_user but no exported symbols for them, breaking bunch of other drivers when built as a module. At the same time, move EXPORT_SYMBOL(__copy_user) and EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's located together with the function definition.

Pull x86 apic updates from Thomas Gleixner: "After stopping the full x86/apic branch, I took some time to go through the first block of patches again, which are mostly cleanups and preparatory work for the irqdomain conversion and ioapic hotplug support. Unfortunaly one of the real problematic commits was right at the beginning, so I rebased this portion of the pending patches without the offenders. It would be great to get this into 3.19. That makes reworking the problematic parts simpler. The usual tip testing did not unearth any issues and it is fully bisectible now. I'm pretty confident that this wont affect the calmness of the xmas season. Changes: - Split the convoluted io_apic.c code into domain specific parts (vector, ioapic, msi, htirq) - Introduce proper helper functions to retrieve irq specific data instead of open coded dereferencing of pointers - Preparatory work for ioapic hotplug and irqdomain conversion - Removal of the non functional pci-ioapic driver - Removal of unused irq entry stubs - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC allocations for everything which is called from there. - Small cleanups and fixes" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) iommu/amd: Use helpers to access irq_cfg data structure associated with IRQ iommu/vt-d: Use helpers to access irq_cfg data structure associated with IRQ x86: irq_remapping: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Use helpers to access irq_cfg data structure associated with IRQ x86, irq: Make MSI and HT_IRQ indepenent of X86_IO_APIC x86, irq: Move IRQ initialization routines from io_apic.c into vector.c x86, irq: Move IOAPIC related declarations from hw_irq.h into io_apic.h x86, irq: Move HT IRQ related code from io_apic.c into htirq.c x86, irq: Move PCI MSI related code from io_apic.c into msi.c x86, irq: Replace printk(KERN_LVL) with pr_lvl() utilities x86, irq: Make UP version of irq_complete_move() an inline stub x86, irq: Move local APIC related code from io_apic.c into vector.c x86, irq: Introduce helpers to access struct irq_cfg x86, irq: Protect __clear_irq_vector() with vector_lock x86, irq: Rename local APIC related functions in io_apic.c as apic_xxx() x86, irq: Refine hw_irq.h to prepare for irqdomain support x86, irq: Convert irq_2_pin list to generic list x86, irq: Kill useless parameter 'irq_attr' of IO_APIC_get_PCI_irq_vector() x86, irq, acpi: Get rid of special handling of GSI for ACPI SCI x86, irq: Introduce helper to check whether an IOAPIC has been registered ...
