If no matching PD is found in ib_uverbs_reg_mr(), then the function
jumps to err_release without setting the return value ret.  This means
that ret will hold the return value of the call to ib_umem_get() a few
lines earlier; if the function reaches the point where it looks for
the PD, we know that ib_umem_get() must have returned 0, so
ib_uverbs_reg_mr() ends up return 0 for a bad PD ID.  Fix this by
setting ret to -EINVAL before jumping to the exit path when no PD is
found.

Driver for the Silicon Motion SM501 multifunction device framebuffer
subsystem.

This driver supports both the CRT and LCD panel heads, with some simple
acceleration for the cursor plotting and support for screen panning.  There
is no current support for bitblt/drawing engines, which should be added at
a later date.

This has been tested on a number of configurations, including PCI and
generic-bus, on PPC, ARM and SH4

Various bug fixes to the at91rm9200 RTC:

 - alarm:  setalarm() should pay attention to the "enabled" flag

 - init:  cleaner handling of the wakeup flags, which cpu init should
   really have set up.  Doing it here is just a workaround.

 - linkage:  since the at91_rtc driver probe() routine is in the init
   section, it should use platform_driver_probe() instead of leaving
   that pointer around in the driver struct after init section removal.

 - linkage:  likewise, remove() belongs in the exit section.

Among other things, the init and alarm changes ensure that this driver
handles the new sysfs "wakealarm" attribute properly.

Some rtc-sa1100 bugfixes:

 - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
   This patch is already in the handhelds.org tree.

 - And the set_alarm() method now handles that flag correctly, rather than
   making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
   warning messages.  (Those calls are best made in suspend/resume methods.)

Note that while this SA1100/PXA RTC is fully capable of waking those ARM
processors from sleep states, that mechanism isn't properly supported on
either processor family, or in this driver.  Some boards have board-specific
PM glue providing partial workarounds for the weak generic PM support.

The problem comes when ks0108/cfag12864b are built-in and no parallel port is
present.  ks0108_init() is called first, as it should be, but fails to load
(as there is no parallel port to use).

After that, cfag12864b_init() gets called, without knowing anything about
ks0108 failed, and calls ks0108_writecontrol(), which dereferences an
uninitialized pointer.

Init order is OK, I think.  The problem is how to stop cfag12864b_init() being
called if ks0108 failed to load.  modprobe does it for us, but, how when
built-in?

This patch provides code paths which allow the natsemi driver to use the

The link state will be left as it was when the driver started and can be
configured via ethtool.  Any PHYs that are present can be accessed via the MII
ioctl()s.

This is useful for systems where the device is connected without a PHY
or where either information or actions outside the scope of the driver
are required in order to use the PHYs.
