2017-01-31[media] pvrusb2-io: Use kmalloc_array() in pvr2_stream_buffer_count()Markus Elfring1-1/+2
A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.

2017-01-27[media] media: Drop FSF's postal address from the source code filesSakari Ailus1-4/+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 Of the 628 removed instances, 578 are outdated.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 $a; close(F);'; done Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>
2016-10-21[media] pvrusb2: don't break long linesMauro Carvalho Chehab1-22/+13
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($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>
2016-02-23[media] pvrusb2-io: no need to check if sp is not NULLMauro Carvalho Chehab1-1/+1
The buffer_complete() routine assumes that sp is not NULL, otherwise it will fail completely. Btw, this is also assumed at pvr2_buffer_queue(), with is the routine that setups the URB handling. So, remove the bogus for the callback at buffer_complete. This fix this smatch warning: drivers/media/usb/pvrusb2/pvrusb2-io.c:476 buffer_complete() warn: variable dereferenced before check 'sp' (see line 472) Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
