2010-12-30[media] ivtv: Add Adaptec Remote ControllerMauro Carvalho Chehab
lirc-i2c implements a get key logic for the Adaptec Remote Controller, at address 0x6b. The only driver that seems to have an Adaptec device is ivtv: $ git grep -i adaptec drivers/media drivers/media/video/cs53l32a.c: * cs53l32a (Adaptec AVC-2010 and AVC-2410) i2c ivtv driver. drivers/media/video/cs53l32a.c: * Audio source switching for Adaptec AVC-2410 added by Trev Jackson drivers/media/video/cs53l32a.c: /* Set cs53l32a internal register for Adaptec 2010/2410 setup */ drivers/media/video/ivtv/ivtv-cards.c:/* Adaptec VideOh! AVC-2410 card */ drivers/media/video/ivtv/ivtv-cards.c: { PCI_DEVICE_ID_IVTV16, IVTV_PCI_ID_ADAPTEC, 0x0093 }, drivers/media/video/ivtv/ivtv-cards.c: .name = "Adaptec VideOh!

So, the logic at lirc_i2c seems to be for Adaptec AVC-2410. As we'll remove lirc_i2c from kernel, move the getkey code to ivtv driver, and use it for AVC-2410.

2010-12-30[media] cx88: Add RC logic for Leadtek PVR 2000Mauro Carvalho Chehab
Currently, lirc-i2c has a decoding logic for Leadtek Remote Control. Move it to cx88, as we intend to remove lirc-i2c. For now, initialize LIRC remote keytable with RC_MAP_EMPTY, as we don't know its keymap yet. It would be nice to later check if is there any file on LIRC userspace with that keytable.

2010-12-30[media] bttv-input: Add a note about PV951 RCMauro Carvalho Chehab

As lirc-i2c will be removed soon, store the difference on a comment inside ir-kbd-i2c, in order to preserve the knowledge we have about that remote controller.

2010-12-30sound: Prevent buffer overflow in OSS load_mixer_volumesDan Rosenberg
The load_mixer_volumes() function, which can be triggered by unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to a buffer overflow. Because the provided "name" argument isn't guaranteed to be NULL terminated at the expected 32 bytes, it's possible to overflow past the end of the last element in the mixer_vols array. Further exploitation can result in an arbitrary kernel write (via subsequent calls to load_mixer_volumes()) leading to privilege escalation, or arbitrary kernel reads via get_mixer_levels(). In addition, the strcmp() may leak bytes beyond the mixer_vols array.

2010-12-30[media] v4l: fix handling of v4l2_input.capabilitiesHans Verkuil
The v4l core sets the v4l2_input.capabilities field based on the supplied v4l2_ioctl_ops. However, several drivers do a memset or memcpy of the v4l2_input struct, thus overwriting that field incorrectly. Either remove the memset (which is already done by the v4l core), or add the proper capabilities field in case of a memcpy.

On Simics, when read N bytes that exceed the amout of data in receive FIFO, we can't read the data out, that is we can't clear the rx FIFO, then the CPU will loop on the espi rx interrupt.

2010-12-29of/flattree: Refactor unflatten_device_tree and add fdt_unflatten_treeStephen Neuendorffer
unflatten_device_tree has two dependencies on things that happen during boot time. Firstly, it references the initial device tree directly. Secondly, it allocates memory using the early boot allocator. This patch factors out these dependencies and uses the new __unflatten_device_tree function to implement a driver-visible fdt_unflatten_tree function, which can be used to unflatten a blob after boot time. V2: - remove extra __va() call - make dt_alloc functions return void *. This doesn't fix the general strangeness in this code that constantly casts back and forth between unsigned long and __be32 * Signed-off-by: Stephen Neuendorffer <stephen.neuendorffer@xilinx.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2010-12-29of/flattree: Add Kconfig for EARLY_FLATTREEStephen Neuendorffer
The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored.

2010-12-29kconfig: fix undesirable side effect of adding "visible" menu attributeJan Beulich
This lead to non-selected, non-user-selectable options to be written out to .config. This is not only pointless, but also preventing the user to be prompted should any of those options eventually become visible (e.g. by de-selecting the *_AUTO options the "visible" attribute was added for. Furthermore it is quite logical for the "visible" attribute of a menu to control the visibility of all contained prompts, which is what the patch does.

2010-12-29spi/omap2_mcspi.c: Force CS to be in inactive state after off-mode transitionGregory CLEMENT
When SPI wake up from OFF mode, CS is in the wrong state: force it to the inactive state. During the system life, I monitored the CS behavior using a oscilloscope. I also activated debug in omap2_mcspi, so I saw when driver disable the clocks and restore context when device is not used.Each time the CS was in the correct state. It was only when system was put suspend to ram with off-mode activated that on resume the CS was in wrong state( ie activated). Changelog: * Change from v1 to v2: - Rebase on linus/master (after 2.6.37-rc1) - Do some clean-up and fix indentation on both patches - Add more explanations for patch 2 * Change from v2 to v3: - Use directly resume function of spi_master instead of using function - from spi_device as Grant Likely pointed it out. - Force this transition explicitly for each CS used by a device. * Change from v3 to v4: - Patch clean-up according to Kevin Hilman and checkpatch. - Now force CS to be in inactive state only if it was inactive when it was suspended. * Change from v4 to v5: - Rebase on linus/master (after 2.6.37-rc3) - Collapse some lines as pointed by Grant Likely - Fix a spelling * Change from v5 to v6: - Rebase on linus/master (after 2.6.37-rc7) - Use CONFIG_SUSPEND instead of CONFIG_PM - Didn't use legacy PM methods anymore. Instead, add a struct dev_pm_ops and add the resume method there. - Fix multi-line comment style * Change from v6 to v7: - Rebase on linus/master (after 2.6.37-rc8) - Drop an extra line Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
