[media] usbvision: don't break long lines

2016-10-21T11:55:11+00:00

Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } Signed-off-by: Mauro Carvalho Chehab

[media] usbvision: revert commit 588afcc1

2016-04-20T18:58:54+00:00

Commit 588afcc1c0e4 ("[media] usbvision fix overflow of interfaces array")' should be reverted, because: * "!dev->actconfig->interface[ifnum]" won't catch a case where the value is not NULL but some garbage. This way the system may crash later with GPF. * "(ifnum >= USB_MAXINTERFACES)" does not cover all the error conditions. "ifnum" should be compared to "dev->actconfig-> desc.bNumInterfaces", i.e. compared to the number of "struct usb_interface" kzalloc()-ed, not to USB_MAXINTERFACES. * There is a "struct usb_device" leak in this error path, as there is usb_get_dev(), but no usb_put_dev() on this path. * There is a bug of the same type several lines below with number of endpoints. The code is accessing hard-coded second endpoint ("interface->endpoint[1].desc") which may not exist. It would be great to handle this in the same patch too. * All the concerns above are resolved by already-accepted commit fa52bd50 ("[media] usbvision: fix crash on detecting device with invalid configuration") * Mailing list message: http://www.spinics.net/lists/linux-media/msg94832.html Signed-off-by: Vladis Dronov Signed-off-by: Hans Verkuil Cc: # for v4.5 Signed-off-by: Mauro Carvalho Chehab

[media] include/media: split I2C headers from V4L2 core

2015-11-17T08:57:11+00:00

Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" 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 Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.
