2015-08-11[media] pctv452e: Replace memset with eth_zero_addrVaishali Thakkar1-1/+1
Use eth_zero_addr to assign the zero address to the given address array instead of memset when second argument is address of zero. Note that the 6 in the third argument of memset appears to represent an ethernet address size (ETH_ALEN).

2015-08-11[media] x86/mm/pat, drivers/media/ivtv: move pat warn and replace WARN() ↵Luis R. Rodriguez1-6/+9
with pr_warn() On built-in kernels this warning will always splat as this is part of the module init. Fix that by shifting the PAT requirement check out under the code that does the "quasi-probe" for the device. This device driver relies on an existing driver to find its own devices, it looks for that device driver and its own found devices, then uses driver_for_each_device() to try to see if it can probe each of those devices as a frambuffer device with ivtvfb_init_card(). We tuck the PAT requiremenet check then on the ivtvfb_init_card() call making the check at least require an ivtv device present before complaining.

2015-08-11[media] pci/Kconfig: don't use MEDIA_ANALOG_TV_SUPPORT for grabber cardsKrzysztof Hałasa1-3/+3
I noticed certain cards are currently under MEDIA_ANALOG_TV_SUPPORT but it seems they are frame grabbers (with CVBS, Svideo etc. inputs) rather than TV receivers (with analog TV tuners). MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems to drive a real camera in a laptop) but it at least doesn't select the TUNERs. Perhaps the following patch would make sense.

2015-08-11[media] v4l2: move tracepoint generation into separate filePhilipp Zabel3-1/+14
To compile videobuf2-core as a module, the vb2_* tracepoints must be exported from the videodev module. Instead of exporting vb2 tracepoint symbols from v4l2-ioctl.c, move the tracepoint generation into a separate file. This patch fixes the following build error in the modpost stage, introduced by 2091f5181c66 ("[media] videobuf2: add trace events"): ERROR: "__tracepoint_vb2_buf_done" undefined!

2015-08-11[media] media: adv7604: reduce support to first (digital) inputWilliam Towle1-3/+14
Using adv7611_read_cable_det() for ADV7612 means that full support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available due to the need for multiple port reads to determine cable detection, and an agreed mechanism for communicating the separate statuses. This patch replaces adv7611_read_cable_det() with a functionally identical copy, commented appropriately. Earlier submissions [leading to commit 8331d30b] also set .cp_csc, which is used in a cp_read() call within adv76xx_log_status().
