Merge tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - Two new dvb frontend drivers: mn88472 and mn88473 - A new driver for some PCIe DVBSky cards - A new remote controller driver: meson-ir - One LIRC staging driver got rewritten and promoted to mainstream: igorplugusb - A new tuner driver (m88rs6000t) - The old omap2 media driver got removed from staging. This driver uses an old DMA API and it is likely broken on recent kernels. Nobody cared enough to fix it - Media bus format moved to a separate header, as DRM will also use the definitions there - mem2mem_testdev were renamed to vim2m, in order to use the same naming convention taken by the other virtual test driver (vivid) - Added a new driver for coda SoC (coda-jpeg) - The cx88 driver got converted to use videobuf2 core - Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc cores - Lots of other fixes, improvements and cleanups on the drivers. * tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (384 commits) [media] mn88473: One function call less in mn88473_init() after error [media] mn88473: Remove uneeded check before release_firmware() [media] lirc_zilog: Deletion of unnecessary checks before vfree() [media] MAINTAINERS: Add myself as img-ir maintainer [media] img-ir: Don't set driver's module owner [media] img-ir: Depend on METAG or MIPS or COMPILE_TEST [media] img-ir/hw: Drop [un]register_decoder declarations [media] img-ir/hw: Fix potential deadlock stopping timer [media] img-ir/hw: Always read data to clear buffer [media] redrat3: ensure dma is setup properly [media] ddbridge: remove unneeded check before dvb_unregister_device() [media] si2157: One function call less in si2157_init() after error [media] tuners: remove uneeded checks before release_firmware() [media] arm: omap2: rx51-peripherals: fix build warning [media] stv090x: add an extra protetion against buffer overflow [media] stv090x: Remove an unreachable code [media] stv090x: Some whitespace cleanups [media] em28xx: checkpatch cleanup: whitespaces/new lines cleanups [media] si2168: add support for firmware files in new format [media] si2168: debug printout for firmware version ...

- * lirc_igorplugusb - USB remote support for LIRC
- *
- * Supports the standard homebrew IgorPlugUSB receiver with Igor's firmware.
- * See http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm
- *
- * The device can only record bursts of up to 36 pulses/spaces.
- * Works fine with RC5. Longer commands lead to device buffer overrun.
- * (Maybe a better firmware or a microcontroller with more ram can help?)

+Driver general quality is not good enough for mainline. Also, other
+device drivers (USB-bridge, tuner) needed for Astrometa receiver in
+question could need some changes. However, if that driver is mainlined
+due to some other device than Astrometa, unrelated TODOs could be
+skipped. In that case rtl28xxu driver needs module parameter to prevent
+driver loading.
+
+Required TODOs:
+* missing lock flags
+* I2C errors
+* tuner sensitivity
+
+*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
+checkpatch.pl tests. I don't want waste my time to review this kind of
+trivial stuff. *Do not* add missing register I/O error checks. Those are
+missing for the reason it is much easier to compare I2C data sniffs when
+there is less lines. Those error checks are about the last thing to be added.
+
+Patches should be submitted to:
+linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>

+Driver general quality is not good enough for mainline. Also, other
+device drivers (USB-bridge, tuner) needed for Astrometa receiver in
+question could need some changes. However, if that driver is mainlined
+due to some other device than Astrometa, unrelated TODOs could be
+skipped. In that case rtl28xxu driver needs module parameter to prevent
+driver loading.
+
+Required TODOs:
+* missing lock flags
+* I2C errors
+* tuner sensitivity
+
+*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
+checkpatch.pl tests. I don't want waste my time to review this kind of
+trivial stuff. *Do not* add missing register I/O error checks. Those are
+missing for the reason it is much easier to compare I2C data sniffs when
+there is less lines. Those error checks are about the last thing to be added.
+
+Patches should be submitted to:
+linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>
