372c931319 USB: yurex: fix control-URB timeout handling
Make sure to always cancel the control URB in write() so that it can be
reused after a timeout or spurious CMD_ACK.

Currently any further write requests after a timeout would fail after
triggering a WARN() in usb_submit_urb() when attempting to submit the
already active URB.

259a252c1f console: Delete dummy con_font_set() and con_font_default() callback implementations
.con_font_set and .con_font_default callbacks should not pass `struct
console_font *` as a parameter, since `struct console_font` is a UAPI
structure.

We are trying to let them use our new kernel font descriptor, `struct
font_desc` instead. To make that work slightly easier, first delete all of
their no-op implementations used by dummy consoles.

This will make KD_FONT_OP_SET and KD_FONT_OP_SET_DEFAULT ioctl() requests
on dummy consoles start to fail and return `-ENOSYS`, which is intended,
since no user should ever expect such operations to succeed on dummy
consoles.

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, the result is that this device cannot
enter the idle state and always stay busy or other non-idle

0cb686692f USB: apple-mfi-fastcharge: don't probe unhandled devices
From: Bastien Nocera <hadess@hadess.net>

Contrary to the comment above the id table, we didn't implement a match
function. This meant that every single Apple device that was already
plugged in to the computer would have its device driver reprobed
when the apple-mfi-fastcharge driver was loaded, eg. the SD card reader
could be reprobed when the apple-mfi-fastcharge after pivoting root
during boot up and the module became available.

Make sure that the driver probe isn't being run for unsupported
devices by adding a match function that checks the product ID, in
addition to the id_table checking the vendor ID.

862ee699fe USB: sisusbvga: Make console support depend on BROKEN
The console part of sisusbvga is broken vs. printk(). It uses in_atomic()
to detect contexts in which it cannot sleep despite the big fat comment in
preempt.h which says: Do not use in_atomic() in driver code.

in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which
means that spin/rw_lock held regions are not detected by it.

There is no way to make this work by handing context information through to
the driver and this only can be solved once the core printk infrastructure
supports sleepable console drivers.

Make it depend on BROKEN for now.

517c4c44b3 usb: Add driver to allow any GPIO to be used for 7211 USB signals
The Broadcom 7211 has new functionality that allows some USB low
speed side band signals, that go from the XHCI host controller to
pins on the chip, to be remapped to use any GPIO pin instead of the
limited set selectable by hardware. This can be done without changing
the standard driver for the host controller. There is currently
support for three USB signals, PWRON, VBUS_PRESENT and PWRFLT. This
driver will allow the remapping of any of these three signals based
on settings in the Device Tree node for the driver. The driver was
written so that it could handle additional signals added in the
future by just adding the correct properties to the DT node.

Below is an example of a DT node that would remap all three
signals:

usb_pinmap: usb-pinmap@22000d0 {
	compatible = "brcm,usb-pinmap";
	reg = <0x22000d0 0x4>;
	in-gpios = <&gpio 18 0>, <&gpio 19 0>;
	brcm,in-functions = "VBUS", "PWRFLT";
	brcm,in-masks = <0x8000 0x40000 0x10000 0x80000>;
	out-gpios = <&gpio 20 0>;
	brcm,out-functions = "PWRON";
	brcm,out-masks = <0x20000 0x800000 0x400000 0x200000>;
	interrupts = <0x0 0xb2 0x4>;
};

ffeb1e9e89 USB: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

313da01ad5 usb: misc: sisusbvga: Move static const tables out to different include file
sisusb_init.h is included by multiple source files, but the big data
tables contained are only referenced by one of them, leaving the tables
'defined but not used' by the remainder.  We have a choice to either
place them inside the source file, taking up may lines and potentially
overwhelming the source file OR tuck them away neatly inside their own
headerfile.  The latter was chosen.

Fixes the following W=1 kernel build warning(s):

2b53a19284 USB: sisusbvga: Fix a potential UB casued by left shifting a negative value
The char buffer buf, receives data directly from user space,
so its content might be negative and its elements are left
shifted to form an unsigned integer.

Since left shifting a negative value is undefined behavior, thus
change the char to u8 to elimintate this UB.

c0e4b3ad67 vt: use newly defined CUR_* macros
We defined macros for all the magic constants in the previous patch. So
let us use the macro in the code now.

No functional change intended.

77bc14f273 vc: switch state to bool
The code currently uses bitfields to store true-false values. Switch all
of that to bools. Apart from the cleanup, it saves 20B of code as many
shifts, ANDs, and ORs became simple movzb's.

b84ae3dc70 vt: introduce enum vc_intensity for intensity
Introduce names (en enum) for 0, 1, and 2 constants. We now have
VCI_HALF_BRIGHT, VCI_NORMAL, and VCI_BOLD instead.

Apart from the cleanup,
1) the enum allows for better type checking, and
2) this saves some code. No more fiddling with bits is needed in
   assembly now. (OTOH, the structure is larger.)

62fb45d317 USB: ch9: add "USB_" prefix in front of TEST defines
For some reason, the TEST_ defines in the usb/ch9.h files did not have
the USB_ prefix on it, making it a bit confusing when reading the file,
as well as not the nicest thing to do in a uapi file.

So fix that up and add the USB_ prefix on to them, and fix up all
in-kernel usages.  This included deleting the duplicate copy in the
net2272.h file.
