staging: omap-thermal: switch mutex to spinlock inside omap-bandgap
Because there is a need to lock inside IRQ handler, this patch
changes the locking mechanism inside the omap-bandgap.[c,h] to
spinlocks. Now this lock is used to protect omap_bandgap struct
during APIs exposed (possibly used in sysfs handling functions)
and inside the ALERT IRQ handler.
Because there are registers shared among the sensors, this lock
is global, not per sensor.
Now arch code has to specify CONFIG_ARCH_HAS_BANDGAP. So, this driver
will be selectable only if the platform reports itself as having a
bandgap device.
Any OMAP variant or any other OMAP version needs to
select ARCH_HAS_BANDGAP
so that the driver will be applicable. A part from that it is
required to device the data structures that maps the registers
and their bitfields. The DT compatible list must also be updated.
This patch improves the code that handles threshold values
by creating single functions that are usable for tcold and
thot. This way we won't have duplicated functionality just
because it is handling different bitfields. Now
the added functions are reused in several places where
it is needed to update any threshold.
This patch also removes macros that are used only inside
the _validate helper function.
In this patch there is also an addition of an extra function
section for Exposed APIs, used outside the omap-bandgap.c,
but inside the omap-thermal driver.
This change improves temp_sensor_unmask_interrupts by:
. renaming it to omap_bandgap_unmask_interrupts
. making it a void function, as there is nothing really to report an error.

staging: comedi: adv_pci1710: restore PCI-1710HG support
The Advantech PCI-1710HG is similar to the PCI-1710 but has a different
set of ranges for analog input (HG = high gain). Because they share the
same PCI vendor and device ID, the adv_pci1710 driver does not currently
distinguish them. This is more of a problem since auto-configuration
code was added to the driver (and manual configuration support removed),
as the PCI-1710HG would be automatically configured as a PCI-1710. More
recently, the unused code for PCI-1710HG support was #ifdef'ed out.
In fact, the PCI-1710 and PCI-1710HG can be distinguished by considering
the PCI subvendor and subdevice IDs according to the following table:
The above information is extracted from Advantech's own GPL'ed Linux
(non-Comedi) driver source from "advdaq-1.10.0001-1.tar.bz2" on their
website.
(0x13fe = PCI_VENDOR_ID_ADVANTECH, 0x10b5 = PCI_VENDOR_ID_PLX, 0x9050 =
PCI_DEVICE_ID_PLX_9050, 0x1000 = PCI_VENDOR_ID_NCR or
PCI_VENDOR_ID_LSI_LOGIC but I assume this subvendor ID was chosen
"randomly".)

The 'data' pointer points to an array of unsigned int values. The number
of values in the array is indicated by insn->n. The number of data
elements is never checked so the dev_dbg() could be trying to access
a 'data' element that is invalid.
