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
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$j\2\3,; print \$_' |\\";
done;
done;
echo "cat > a && mv a \$i; done";
);
echo "Handling documentation..." >&2;
echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
(
cd include/$MAIN_DIR;
for j in $DIRS; do
for i in $(ls $j); do
echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
done;
done;
echo "cat > a && mv a \$i; done"
);
) >script && . ./script
