av7110: check for negative array offset

2011-04-30T14:53:04+00:00

commit cb26a24ee9706473f31d34cc259f4dcf45cd0644 upstream. info->num comes from the user. It's type int. If the user passes in a negative value that would cause memory corruption. Signed-off-by: Dan Carpenter Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

V4L/DVB (13079): dib0700: fixed xc2028 firmware loading kernel oops

2009-12-08T19:17:08+00:00

commit 7646b9de26c54cf4bc9c446d7ada9f91ece31e0a upstream. Fixing kernel oops when driver attemps to load xc2028 firmware. Note by djh: the patch contribute by Martin is a port of a fix I made during the PCTV 340e development. It's a temporary workaround that fixes a regression (an OOPS condition) and the real fix should be in the code that manages the i2c master on the dib7000p. But this fix does address the immmediate regression and should be merged upstream until we do a cleaner fix.

DVB: s5h1409: Perform s5h1409 soft reset after tuning

2009-03-17T00:53:02+00:00

(cherry picked from commit 67e70baf043cfdcdaf5972bc94be82632071536b) Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it to know that the tuner has been told to change frequencies. This change changes the behavior from "random tuning times between 500ms to complete tuning lock failures" to "tuning lock consistently within 700ms". Thanks to Robert Krakora for doing initial testing of the patch on the KWorld 330U. Thanks to Andy Walls for doing testing of the patch on the HVR-1600. Thanks to Michael Krufky for doing additional testing. Signed-off-by: Devin Heitmueller Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

By performing a soft reset after the tuning call (which is consistent with how the Pinnacle 801e Windows driver behaves), you get a demod lock inside of 300ms Signed-off-by: Devin Heitmueller Signed-off-by: Michael Krufky Acked-by: Steven Toth Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

V4L/DVB (9043): S5H1420: Fix size of shadow-array to avoid overflow

2008-10-05T02:01:21+00:00

The array size of 'shadow' still needs to be fixed in order to not overflow when reading register 0x00. Thanks to Oliver Endriss for pointing that out. Signed-off-by: Patrick Boettcher Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (9037): Fix support for Hauppauge Nova-S SE

2008-10-05T02:00:46+00:00

Different backends have different input busses (saa7146, flexcop). To reflect that a config-option to the s5h1420-driver was added which makes the output mode selectable. Furthermore the s5h1420-driver is now doing the same i2c-method as it was done before adding support for other i2c-users. This patch needs to go into the current release of the kernel, as this driver is currently broken. (Thanks to Eberhard Kaltenhaeuser for helping out to debug this issue.)

V4L/DVB (9029): Fix deadlock in demux code

2008-10-05T01:59:55+00:00

The functions dvb_dmxdev_section_callback, dvb_dmxdev_ts_callback, dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and dvb_dmx_swfilter_204 may be called from both interrupt and process context. Therefore they need to be protected by spin_lock_irqsave() instead of spin_lock(). This fixes a deadlock discovered by lockdep. Signed-off-by: Andreas Oberritter Signed-off-by: Mauro Carvalho Chehab
