The company that developed this driver has long gone and the hardware is hard to find. As it relies on a legacy set of kABI symbols and nobody seems to care about it, remove it. - several improvements at rtl2832 driver - conversion on cx28521 and au0828 to use videobuf2 (VB2) - several improvements, fixups and board additions * tag 'media/v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (321 commits) [media] dvb_net: Convert local hex dump to print_hex_dump_debug [media] dvb_net: Use standard debugging facilities [media] dvb_net: Use vsprintf %pM extension to print Ethernet addresses [media] staging: lirc_serial: adjust boolean assignments [media] stb0899: use sign_extend32() for sign extension [media] si2168: add support for 1.7MHz bandwidth [media] si2168: return error if set_frontend is called with invalid parameters [media] lirc_dev: avoid potential null-dereference [media] mn88472: simplify bandwidth registers setting code [media] dvb: tc90522: re-add symbol-rate report [media] lmedm04: add read snr, signal strength and ber call backs [media] lmedm04: Create frontend call back for read status [media] lmedm04: create frontend callbacks for signal/snr/ber/ucblocks [media] lmedm04: Fix usb_submit_urb BOGUS urb xfer, pipe 1 != type 3 in interrupt urb [media] lmedm04: Increase Interupt due time to 200 msec [media] cx88-dvb: whitespace cleanup [media] rtl28xxu: properly initialize pdata [media] rtl2832: declare functions as static [media] rtl2830: declare functions as static [media] rtl2832_sdr: add kernel-doc comments for platform_data ...
