Merge tag 'media/v3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - new IR driver: hix5hd2-ir - the virtual test driver (vivi) was replaced by vivid, with has an almost complete set of features to emulate most v4l2 devices and properly test all sorts of userspace apps - the as102 driver had several bugs fixed and was properly split into a frontend and a core driver. With that, it got promoted from staging into mainstream - one new CI driver got added for CIMaX SP2/SP2HF (sp2 driver) - one new frontend driver for Toshiba ISDB-T/ISDB-S demod (tc90522) - one new PCI driver for ISDB-T/ISDB-S (pt3 driver) - saa7134 driver got support for go7007-based devices - added a new PCI driver for Techwell 68xx chipsets (tw68) - a new platform driver was added (coda) - new tuner drivers: mxl301rf and qm1d1c0042 - a new DVB USB driver was added for DVBSky S860 & similar devices - added a new SDR driver (hackrf) - usbtv got audio support - several platform drivers are now compiled with COMPILE_TEST - a series of compiler fixup patches, making sparse/spatch happier with the media stuff and removing several warnings, especially on those platform drivers that didn't use to compile on x86 - Support for several new modern devices got added - lots of other fixes, improvements and cleanups * tag 'media/v3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (544 commits) [media] ir-hix5hd2: fix build on c6x arch [media] pt3: fix DTV FE I2C driver load error paths Revert "[media] media: em28xx - remove reset_resume interface" [media] exynos4-is: fix some warnings when compiling on arm64 [media] usb drivers: use %zu instead of %zd [media] pci drivers: use %zu instead of %zd [media] dvb-frontends: use %zu instead of %zd [media] s5p-mfc: Fix several printk warnings [media] s5p_mfc_opr: Fix warnings [media] ti-vpe: Fix typecast [media] s3c-camif: fix dma_addr_t printks [media] s5p_mfc_opr_v6: get rid of warnings when compiled with 64 bits [media] s5p_mfc_opr_v5: Fix lots of warnings on x86_64 [media] em28xx: Fix identation [media] drxd: remove a dead code [media] saa7146: remove return after BUG() [media] cx88: remove return after BUG() [media] cx88: fix cards table CodingStyle [media] radio-sf16fmr2: declare some structs as static [media] radio-sf16fmi: declare pnp_attached as static ...
