Sakari Ailus bcb63314e2 [media] media: Drop FSF's postal address from the source code files
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outdated.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

Max Kellermann bd336e6344 [media] dvb: make DVB frontend *_ops instances "const"
These are immutable.  Making them "const" allows the compiler to move
them to the "rodata" section.

Note that cxd2841er_t_c_ops cannot be made "const", because
cxd2841er_attach() modifies it.  Ouch!

Mauro Carvalho Chehab 0d43c0ff8b [media] cinergyT2-fe: don't do DMA on stack
The USB control messages require DMA to work. We cannot pass
a stack-allocated buffer, as it is not warranted that the
stack would be into a DMA enabled area.

Mauro Carvalho Chehab c2730eef5f [media] cinergyT2-fe: cache stats at cinergyt2_fe_read_status()
Instead of sending USB commands for every stats call, collect
them once, when status is updated. As the frontend kthread
will call it on every few seconds, the stats will still be
collected.

Besides reducing the amount of USB/I2C transfers, this also
warrants that all stats will be collected at the same time,
and makes easier to convert it to DVBv5 stats in the future.

Mauro Carvalho Chehab 0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.
