18bcbcfe9c USB: misc: legousbtower: semaphore to mutex
The dev->sem conforms to mutex style usage. This patch converts it to use
the struct mutex type, and new API.

There is also a small style fix around this comment,

/* unlock here as tower_delete frees dev */

Where I broke the line up to meet the 80 char limit.

f08812d5eb USB: FIx locks and urb->status in adutux (updated)
Two main issues fixed here are:
 - An improper use of in-struct lock to protect an open count
 - Use of urb status for -EINPROGRESS

Also, along the way:
 - Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
   to use usb_unlink_urb whatsoever in this driver, and the old use of
   usb_kill_urb was outright racy (it unlinked and immediately freed).
 - Fix indentation in adu_write. Looks like it was damaged by a script.
 - Vitaly wants -EBUSY on multiply opens.
 - bInterval was taken from a wrong endpoint.

parport_generic_irq()'s second arg makes its first arg completely

e400b6ec4e vt/vgacon: Check if screen resize request comes from userspace
Various console drivers are able to resize the screen via the con_resize()
hook.  This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's.  One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware.  However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.

To work around this problem, add an extra parameter to con_resize().  This
parameter is ignored by drivers except for vgacon.  If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success.  If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware.  The
latter is the more correct behavior.

With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.
