Pull kbuild updates from Michal Marek:
- Make <modname>-m in makefiles work like <modname>-y and fix the
fallout
- Minor genksyms fix
- Fix race with make -j install modules_install
- Move -Wsign-compare from make W=1 to W=2
- Other minor fixes
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kbuild: Demote 'sign-compare' warning to W=2
Makefile: revert "Makefile: Document ability to make file.lst and file.S" partially
kbuild: Do not run modules_install and install in paralel
genksyms: Handle string literals with spaces in reference files
fixdep: constify strrcmp arguments
ath10k: Fix build with CONFIG_THERMAL=m
Revert "drm: Hack around CONFIG_AGP=m build failures"
kbuild: Allow to specify composite modules with modname-m
staging/ad7606: Actually build the interface modules
Directly manipulate the controller regsiter to suspend the usb bus
for HNP is not the proper way, this should be done through the usbcore
by usb autosuspend. So to start HNP, autosuspend support should be
added for OTG devices interface driver if it's not enabled.

call to of_find_property() before of_property_read_u32() is unnecessary.
of_property_read_u32() anyway calls to of_find_property() only.

Since we need to mount debugfs to show/store the things we
want to debug, it is duplicated to add another configuration
to enable it. Meanwhile, with CONFIG_USB_CHIPIDEA_DEBUG,
we can't support chipidea debugfs at runtime.

_hardware_enqueue() didn't check for errors when using
add_td_to_list() which can fail if dma_pool_alloc fails, thus
causing a kernel panic when lastnode->ptr is NULL.

This allows to write
drm-$(CONFIG_AGP) += drm_agpsupport.o
without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support
this syntax for modules, since built-in code depending on something
modular cannot work and init/Makefile actually relies on the current
semantics. There are a few drivers which adapted to the current
semantics out of necessity; these are fixed to also work when the
respective subsystem is modular.

Since the ci->role will be set after the host role start is complete, there
will be nobody cared irq during start host if usb irq enabled. This error
can be reproduced on i.mx6 sololite EVK board by:
1. disable otg id irq(IDIE) and disable all real otg properties of usbotg1
in dts.
2. boot up the board with ID cable and usb device connected.
3. echo gadget > /sys/kernel/debug/ci_hdrc.0/role
4. echo host > /sys/kernel/debug/ci_hdrc.0/role
5. irq 212: nobody cared.

Some i.mx platforms need three clocks to let controller work, but
others only need one, refine clock operation to adapt for all
platforms, it fixes a regression found at i.mx27.

Some HW design may use ID pin state to control vbus for otg port,
so before host role start, the vbus is already turned on, in this
case, we do not need wait vbus dropping below BSV.
