      [media] marvell-ccic/mmp-driver.c: simplify use of devm_ioremap_resource · 5be789fc
      Julia Lawall authored 
      Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@
- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
// </smpl>

      [media] siano: fix divide error on 0 counters · ec532503
      Bjørn Mork authored 
      GIT_AUTHOR_DATE=1376465691
I took a quick look at the code and wonder if the problem is caused by
an initial zero statistics message?  This is all just a wild guess, but
if it is correct, then the attached untested patch might fix it...

      [media] cx23885: Add DTV support for Mygica X8502/X8507 boards · 0d1b5265
      Mauro Carvalho Chehab authored 
      Those boards were missing the ISDB-T support.
Most of the work on this patch were done by Alfredo.
My work here were to port this patch from Kernel 3.2 to upstream,
fix the issue caused by the set_frontend bad hook, and add the
Kconfig bits.
Tested on a X8502 board rebranded as:
"Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800.

      [media] cx23885-dvb: use a better approach to hook set_frontend · 15472faf
      Mauro Carvalho Chehab authored 
      When the frontend drivers got converted to DVBv5 API, the original
hook that tracked when a frontend is set got removed, being replaced
by an approach that would use the gate control. That doesn't work
fine with some boards. Also, the code were called more times than
desired.
Replace it by a logic that will hook the dvb set_frontend ops,
with works with both DVBv3 and DVBv5 calls.
Tested on a Mygica X8502 OEM board.
