usb: gadget: Use usb_put_function instead of usb_remove_function
When the gadget is disabled with writing "0" to the "enable" attribute,
usb_remove_config() is called, and it calls remove_config(), which in
turn removes a function (list_del(&f->list)) from a list of functions
in the configuration, then calls e.g. acm function's unbind
(acm_unbind()),
then calls slp_multi_unbind_config(), which
calls slp_multi_unbind_enabled_functions(), which, for the acm function,
calls acm_function_unbind_config() which then does usb_remove_config()
and the latter attempts to once again remove a function
(list_del(&f->list)) from a list of functions in the configuration.
Since the list_head of an already deleted entry has LIST_POISON1 and
LIST_POISON2 in its prev and next pointers, dereferencing them in
list_del() causes a page fault.
The fix is to use usb_put_function instead, because when it is called
the function is already removed.

the places usb_get/put_function_instance() and usb_get/put_function()

pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodes
One of remaining limitations of current pinctrl-samsung driver was
the inability to parse multiple pinmux/pinconf group nodes grouped
inside a single device tree node. It made defining groups of pins for
single purpose, but with different parameters very inconvenient.
This patch implements Tegra-like support for grouping multiple pinctrl
groups inside one device tree node, by completely changing the way
pin groups and functions are parsed from device tree. The code creating
pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while
the initial creation of groups and functions has been completely
rewritten with following assumptions:
- each group consists of just one pin and does not depend on data
from device tree,
- each function is represented by a device tree child node of the
pin controller, which in turn can contain multiple child nodes
for pins that need to have different configuration values.
Device Tree bindings are fully backwards compatible. New functionality
can be used by defining a new pinctrl group consisting of several child
nodes, as on following example:
sd4_bus8: sd4-bus-width8 {
part-1 {
samsung,pins = "gpk0-3", "gpk0-4",
"gpk0-5", "gpk0-6";
samsung,pin-function = <3>;
samsung,pin-pud = <3>;
samsung,pin-drv = <3>;
};
part-2 {
samsung,pins = "gpk1-3", "gpk1-4",
"gpk1-5", "gpk1-6";
samsung,pin-function = <4>;
samsung,pin-pud = <4>;
samsung,pin-drv = <3>;
};

usb: usb5303: add support for reference clock specified in device tree
USB3503 chip supports 8 values of reference clock. The value is
specified by REF_SEL[1:0] pins and INT_N line. This patch add support
for getting 'refclk' clock, enabling it and setting INT_N line according
to the value of the gathered clock. If no clock has been specified,
driver defaults to the old behaviour (assuming that clock has been
specified by REF_SEL pins from primary reference clock frequencies
table).

ARM: dts: exynos4412-odroid*: fix sleep state for eMMC_nDET pin
During system sleep, eMMC must be put into reset state with eMMC_nDET line.
This patch adds proper configuration for eMMC_nDET pin in sleep state, so
now board finally correctly operates after suspend/resume cycle.

drm/exynos: use a new anon file for exynos gem mmaper
This patch resolves potential deadlock issue that can be incurred
by changing file->f_op and filp->private_data to exynos specific

To resolve this issue, this patch creates a new anon file dedicated
to exynos specific mmaper, and making it used instead of existing one.
