Pull second set of media updates from Mauro Carvalho Chehab: - radio API: add support to work with radio frequency bands - new AM/FM radio drivers: radio-shark, radio-shark2 - new Remote Controller USB driver: iguanair - conversion of several drivers to the v4l2 core control framework - new board additions at existing drivers - the remaining (and vast majority of the patches) are due to drivers/DocBook fixes/cleanups. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (154 commits) [media] radio-tea5777: use library for 64bits div [media] tlg2300: Declare MODULE_FIRMWARE usage [media] lgs8gxx: Declare MODULE_FIRMWARE usage [media] xc5000: Add MODULE_FIRMWARE statements [media] s2255drv: Add MODULE_FIRMWARE statement [media] dib8000: move dereference after check for NULL [media] Documentation: Update cardlists [media] bttv: add support for Aposonic W-DVR [media] cx25821: Remove bad strcpy to read-only char* [media] pms.c: remove duplicated include [media] smiapp-core.c: remove duplicated include [media] via-camera: pass correct format settings to sensor [media] rtl2832.c: minor cleanup [media] Add support for the IguanaWorks USB IR Transceiver [media] Minor cleanups for MCE USB [media] drivers/media/dvb/siano/smscoreapi.c: use list_for_each_entry [media] Use a named union in struct v4l2_ioctl_info [media] mceusb: Add Twisted Melon USB IDs [media] staging/media/solo6x10: use module_pci_driver macro [media] staging/media/dt3155v4l: use module_pci_driver macro ...
