Replace the non-standard vendor prefix stm with st for

since the I2C Core strips them away from the DT provided compatible

Determining which kernel config options need to be enabled for a
given devicetree can be a painful process.  Create a new tool to
find the drivers that may match a devicetree node compatible,
find the kernel config options that enable the driver, and
optionally report whether the kernel config option is enabled.

Fix a memory leak resulting from memory allocation in safe_name().
This patch fixes all call sites of safe_name().

Mathieu Malaterre reported the memory leak on boot:

On my PowerMac device-tree would generate a duplicate name:

[    0.023043] device-tree: Duplicate name in PowerPC,G4@0, renamed to "l2-cache#1"

in this case a newly allocated name is generated by `safe_name`. However
in this case it is never deallocated.

The bug was found using kmemleak reported as:

The arch code calls of_platform_populate() with default match table
when it wants to populate default bus.

This patch introduce a new of_platform_default_populate_init() and make it
arch_initcall_sync(it should be later than some iommu configration, eg,
of_iommu_init() and swiotlb_late_init in arm64), then we can finish above
job in common method.

In order to avoid the default bus being populated twice, simply checking
the flag of bus node whether has be set OF_POPULATED_BUS or not.

After that, we can safely remove the caller in arch code.

Btw, add debug print in of_platform_populate(), and use __func__ to
print function's name of of_platform_bus_create().

The of_iommu_init() is called multiple times by arch code,
make it postcore_initcall_sync, then we can drop relevant
calls fully.

Note, the IOMMUs should have a chance to perform some basic
initialisation before we start adding masters to them. So
postcore_initcall_sync is good choice, it ensures of_iommu_init()
called before of_platform_populate.

 "A new bunch of GPIO fixes for v4.7.

  This time I am very grateful that Ricardo Ribalda Delgado went in and
  fixed my stupid refcounting mistakes in the removal path for GPIO

  exploded on OMAP and it fixes their problem.  Now it should be (more)
  solid.

  stable.

  Summary:

   - Fix a NULL pointer dereference when we are searching the GPIO
     device list but one of the devices have been removed (struct
     gpio_chip pointer is NULL).

   - Fix unaligned reference counters: we were ending on +3 after all
     said and done.  It should be 0.  Remove an extraneous get_device(),
     and call cdev_del() followed by device_del() in gpiochip_remove()
     instead and the count goes to zero and calls the release() function
     properly.

   - Fix a compile warning due to a missing #include in the OF/device
     tree portions.

   - Select ANON_INODES for GPIOLIB, we're using that for our character
     device.  Some randconfig tests disclosed the problem.

     are in bytes or sectors (SCSI optimal is in blocks and the queue
