commit 340a30c5 "s2255drv: upgrade to videobuf2" changed the API used by the s2255 driver, but did not modify the Kconfig statement, which can lead to build errors when no other driver already uses VIDEOBUF2_VMALLOC. This patch does the necessary Kconfig change. Signed-off-by:

That tuner driver is mainly for DVB API, but there is some V4L2 API controls for SDR usage. Make driver compile conditional so that V4L2 is not mandatory. Without the V4L2 support driver is build as a DVB only, without SDR controls. Fixes following errors reported by kbuild test robot: ERROR: "v4l2_ctrl_auto_cluster" [drivers/media/tuners/e4000.ko] undefined! ERROR: "v4l2_ctrl_new_std" [drivers/media/tuners/e4000.ko] undefined!

Exporting functions for hardware filter is a bad idea, as it breaks compilation if: CONFIG_DVB_USB_AF9035=y CONFIG_DVB_AF9033=m Because the PID filter function calls would be hardcoded at af9035. The same doesn't happen with af9033_attach() because the dvb_attach() doesn't hardcode it. Instead, it dynamically links it at runtime. However, calling dvb_attach() multiple times is problematic, as it increments module kref. So, the better is to pass one parameter for the af9033 module to fill the hardware filters, and then use it inside af9035. Signed-off-by:

PID filters are property of af9033 demod. Use PID filters from af9033 driver as it provides those now. Allow possible dual mode on USB 1.1 mode too as bandwidth could be just enough when filters are used on both frontends. Signed-off-by:

The calculated values for the minlen and maxlen fields, which were rounded to multiples of 2 and clamped to a valid range, were left unused. Use them in the calculation of the register value rather than using the raw input minlen and maxlen.

The JVC timings included timings intended for the secondary decoder (which matches messages with no leader), however they were in the wrong part of the timings structure, repeating s00 and s01 rather than being in s10 and s11. Distinct repeat timings can't be properly supported yet for JVC anyway since the scancode callback cannot determine which decoder matched the message, so for now remove these timings and don't bother to enable the secondary decoder. This fixes the following warnings with W=1: drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: initialized field overwritten [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +76 :3: warning: (near initialization for ‘img_ir_jvc.timings.s00’) [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +81 :3: warning: initialized field overwritten [-Woverride-init] drivers/media/rc/img-ir/img-ir-jvc.c +81 :3: warning: (near initialization for ‘img_ir_jvc.timings.s01’) [-Woverride-init] Reported-by:

Implement SDR driver for Realtek RTL2832U chip as a DVB extension module. SDR module is attached by DVB USB RTL28XXU driver as a DVB SEC (satellite equipment controller) module. Abusing unused SEC here has no harm as that is DVB-T only frontend. SDR functionality is provided by RTL2832 DVB-T demodulator. I suspect it is originally planned for DAB and FM, but it could be abused general SDR, due to modern silicon tuners that has wide frequency range and a lot of configurable parameters (filters, gains, ...). http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/44461Signed-off-by:
