* media: gspca: Stop using GFP_DMA for buffers for USB bulk transfersHans de Goede2018-05-051-1/+1
| | | | | | | | | | The recent "x86 ZONE_DMA love" discussion at LSF/MM pointed out that some gspca sub-drivvers are using GFP_DMA to allocate buffers which are used for USB bulk transfers, there is absolutely no need for this, drop it.

| | | | | | | | | | | | | | | | | Use a more typical logging style. The current macro hides the gspca_dev argument so add it to the macro uses instead.

* [media] media: Drop FSF's postal address from the source code filesSakari Ailus2017-01-271-4/+0
| | | | | | | | | | | | | | | | | | | | | Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", <F>); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>

* [media] gspca: don't break long linesMauro Carvalho Chehab2016-10-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. </script> 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 $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* [media] gspca: store current mode instead of individual parametersOndrej Zary2013-09-261-1/+1
| | | | | | | | | | Store complete current mode (struct v4l2_pix_format) in struct gspca_dev instead of separate pixfmt, width and height parameters. This is a preparation for variable resolution support.

* [media] gspca: Remove gspca-specific debug magicTheodore Kilgore2013-03-051-3/+3
| | | | | | | | | | | Instead use v4l2_dbg and v4l2_err. Note that the PDEBUG macro is kept to make this patch-set less invasive, but it is simply a wrapper around v4l2_dbg now. Most of the other changes are there to make the dev parameter for the v4l2_xxx macros available everywhere we do logging.

* [media] gspca: Don't set gspca_dev->dev to NULL before stop0Hans de Goede2012-09-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit a3d6e8cc0e6ddc8b3cfdeb3c979f07ed1aa528b3 gspca_dev->dev is set to NULL on disconnect, before calling stop0. The plan was to get rid of gspca_dev->present and instead simply check for gspca_dev->dev everywhere where we were checking for present. This should be race free since all users of gspca_dev->dev hold the usb_lock, or so I thought. But I was wrong, drivers which use a work-queue + synchronous bulk transfers to get the video data don't hold the usb_lock while doing so, their stop0 callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore after the stop0 call, but they might be dereferincing it before, so we should not set gspca_dev->dev to NULL on disconnect before calling stop0. This also means that the workqueue functions in these drivers cannot use gspca_dev->dev to check if they need to stop because of disconnection, so we will need to keep gspca_dev->present around, and set that to 0 on disconnect, before calling stop0. Unfortunately as part of the plan to remove gspca_dev->present, these workqueues where already moved over to checking for gspca_dev->dev instead of gspca_dev->present as part of commit 254902b01d2acc6aced99ec17caa4c6cd890cdea, so this patch also reverts those parts of that commit.
