For simple modules that contain a single platform_driver without any
additional setup code then ends up being a block of duplicated
boilerplate.  This patch adds a new macro,
module_platform_driver_probe(), which replaces the
module_init()/module_exit() registrations with template functions.

This macro use the same idea of module_platform_driver().

This macro is useful to stop the misuse of module_platform_driver() for
removing the platform_driver_probe() boilerplate.

Inside bus_add_driver(), one device might be added(device_add()) into
the bus or probed which is triggered by deferred probe
just after completing of driver_attach() and before
'klist_add_tail(&priv->knode_bus, &bus->p->klist_drivers)',
so the device won't be probed by this driver.

This patch moves the below line

	'klist_add_tail(&priv->knode_bus, &bus->p->klist_drivers)'

Dave Jones hit this assert when doing a compile on recent git, with
CONFIG_XFS_DEBUG enabled:

XFS: Assertion failed: (char *)dup - (char *)hdr == be16_to_cpu(*xfs_dir2_data_unused_tag_p(dup)), file: fs/xfs/xfs_dir2_data.c, line: 828

Upon further digging, the tag found by xfs_dir2_data_unused_tag_p(dup)
contained "2" and not the proper offset, and I found that this value was
changed after the memmoves under "Use a stale leaf for our new entry."
in xfs_dir2_block_addname(), i.e.

                        memmove(&blp[mid + 1], &blp[mid],
                                (highstale - mid) * sizeof(*blp));

overwrote it.

What has happened is that the previous call to xfs_dir2_block_compact()
has rearranged things; it changes btp->count as well as the
blp array.  So after we make that call, we must recalculate the
proper pointer to the leaf entries by making another call to
xfs_dir2_block_leaf_p().

Dave provided a metadump image which led to a simple reproducer
(create a particular filename in the affected directory) and this
resolves the testcase as well as the bug on his live system.
