2013-09-26hv: move ringbuffer bus attributes to dev_groupsGreg Kroah-Hartman-84/+146
This moves the ringbuffer bus attributes to the dev_groups structure, deletes the now unneeded struct hv_device_info, and removes some now unused functions, and variables as everything is now moved to the dev_groups structure, dev_attrs is no longer needed.

2013-09-26hv: delete struct hv_dev_port_infoGreg Kroah-Hartman-42/+17
It's no longer needed, and the struct hv_ring_buffer_debug_info structure shouldn't be "global" so move it to the local .h file instead. Tested-by: "K. Y. Srinivasan" <kys@microsoft.com> Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-09-26hv: make "monitor_pages" a "real" pointer arrayGreg Kroah-Hartman-18/+15
monitor_pages was a void pointer, containing an unknown number of arrays that we just "knew" were a child and parent array of a specific size. Instead of that implicit knowledge, let's make them a real pointer, allowing us to have type safety, and a semblance of sane addressing schemes. Tested-by: "K. Y.

2013-09-26hv: use dev_groups for device attributesGreg Kroah-Hartman-7/+18
This patch is the first in a series that moves the hv bus code to use the dev_groups field instead of dev_attrs, as dev_attrs is going away in future kernel releases. It moves the id sysfs file to the dev_groups structure, and creates the needed show/store functions, instead of relying on one "universal" function for this. By doing this, it removes the need for this to be in a temporary structure. Tested-by: "K. Y.

bmp085_get_of_properties() is called by bmp085_init_client() which is called by bmp085_probe() which is an EXPORT_SYMBOL_GPL function. bmp085_probe() is really used as a probe function by another modules (e.g. bmp085-i2c.c, bmp085-spi.c). Except bmp085_get_of_properties(), all functions have no '__init', so need remove '__init' from bmp085_get_of_properties() too, or at least, it will report related warning: WARNING: vmlinux.o(.text+0x4c8a07): Section mismatch in reference from the variable .LM171 to the variable .init.text:_bmp085_get_of_properties The function .LM171() references the variable __init _bmp085_get_of_properties.

One to watch out for in future. A number of driver specific fixes 1) at91 - fix a overflow in clock rate computation 2) dummy - Kconfig dependency issue 3) isl29018 - uninitialized value 4) hmc5843 - measurement conversion bug introduced by recent cleanup. 5) ade7854-spi - wrong return value. Some IIO core fixes 1) Wrong value picked up for event code creation for a modified channel 2) A null dereference on failure to initialize a buffer after no buffer has been in use, when using the available_scan_masks approach. 3) Sampling not stopped when a device is removed. Effects forced removal such as hot unplugging. 4) Prevent device going away if a chrdev is still open in userspace. 5) Prevent race on chardev opening and device being freed. 6) Add a missing iio_buffer_init in the call back buffer. These last few are the first part of a set from Lars-Peter Clausen who has been taking a closer look at our removal paths and buffer handling than anyone has for quite some time.
