Geert Uytterhoeven 4360fa22ad drivers: misc: ti-st: Use int instead of fuzzy char for callback status
On mips and parisc:

    drivers/bluetooth/btwilink.c: In function 'ti_st_open':
    drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow]
       hst->reg_status = -EINPROGRESS;

    drivers/nfc/nfcwilink.c: In function 'nfcwilink_open':
    drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow]
      drv->st_register_cb_status = -EINPROGRESS;

There are actually two issues:
  1. Whether "char" is signed or unsigned depends on the architecture.
     As the completion callback data is used to pass a (negative) error
     code, it should always be signed.
  2. EINPROGRESS is 150 on mips, 245 on parisc.
     Hence -EINPROGRESS doesn't fit in a signed 8-bit number.

Change the callback status from "char" to "int" to fix these.

Mauro Carvalho Chehab eb4b0ec75e [media] include/media: move platform_data to linux/platform_data/media
Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.

The headers were moved with:
	mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/

And the references fixed with this script:
    MAIN_DIR="linux/platform_data/"
    PREV_DIR="media/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);

Mauro Carvalho Chehab d647f0b70c [media] include/media: move driver interface headers to a separate dir
Let's not mix headers used by the core with those headers that
are needed by some driver-specific interface header.

The headers used on drivers were manually moved using:
    mkdir include/media/drv-intf/
    git mv include/media/cx2341x.h include/media/cx25840.h \
	include/media/exynos-fimc.h include/media/msp3400.h \
	include/media/s3c_camif.h include/media/saa7146.h \
	include/media/saa7146_vv.h  include/media/sh_mobile_ceu.h \
	include/media/sh_mobile_csi2.h include/media/sh_vou.h \
	include/media/si476x.h include/media/soc_mediabus.h \
	include/media/tea575x.h include/media/drv-intf/

And the references for those headers were corrected using:

    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="drv-intf/"

    echo "Checking affected files" >&2
    for i in $DIRS; do

Arnd Bergmann 78e9b7de78 [media] wl128x-radio really depends on TI_ST
All other drivers using the TI_ST infrastructure use
'depends on' for this symbol, and it makes no sense
to only enable that if CONFIG_NET is enable, because
the radio driver also depends on CONFIG_NET itself:

ERROR: "skb_queue_purge" [drivers/media/radio/wl128x/fm_drv.ko] undefined!
ERROR: "skb_push" [drivers/media/radio/wl128x/fm_drv.ko] undefined!
ERROR: "skb_pull" [drivers/media/radio/wl128x/fm_drv.ko] undefined!

Making the driver dependency explicit solves randconfig

Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

Sebastian Reichel 98bea620c7 [media] si4713: add device tree support
Add device tree support by changing the device registration order.
In the device tree the si4713 node is a normal I2C device, which
will be probed as such. Thus the V4L device must be probed from
the I2C device and not the other way around.
