[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09Z

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 Of the 628 removed instances, 578 are outdated.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("", ); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\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

Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

[media] media: dvb_ringbuffer: Add memory barriers

2016-07-09T10:57:47Z

Implement memory barriers according to Documentation/circular-buffers.txt: - use smp_store_release() to update ringbuffer read/write pointers - use smp_load_acquire() to load write pointer on reader side - use ACCESS_ONCE() to load read pointer on writer side This fixes data stream corruptions observed e.g. on an ARM Cortex-A9 quad core system with different types (PCI, USB) of DVB tuners.

[media] ngene: properly handle __user ptr

2014-09-08T13:00:52Z

Sparse is complaining about ngene's bad usage of a __user ptr: >> drivers/media/pci/ngene/ngene-dvb.c:62:48: sparse: incorrect type in argument 2 (different address spaces) drivers/media/pci/ngene/ngene-dvb.c:62:48: expected unsigned char const [usertype] *buf drivers/media/pci/ngene/ngene-dvb.c:62:48: got char const [noderef] *buf As this is intercepting a .write() file ops, we can't just memcpy. We need to use copy_from_user. Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab

[media] dvb: move the dvb core one level up

2012-08-14T02:08:14Z

just like the V4L2 core, move the DVB core to drivers/media, as the intention is to get rid of both "video" and "dvb" directories. Signed-off-by: Mauro Carvalho Chehab
