2015-02-03[media] rtl2832: add platform data callbacks for exported resourcesAntti Palosaari2-8/+89
Add callback for all of those functions which are currently exported using EXPORT_SYMBOL. That allows us convert every user to callbacks and eventually all exported symbols could be removed. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-02-03[media] rtl2830: implement own I2C lockingAntti Palosaari2-7/+39
Own I2C locking is needed due to two special reasons: 1) Chips uses multiple register pages/banks on single I2C slave. Page is changed via I2C register access. 2) Chip offers muxed/gated I2C adapter for tuner. Gate/mux is controlled by I2C register access. Due to these reasons, I2C locking did not fit very well.

Yet, the entire logic that checks for those registration values is too complex. So, better to add an explicit check, just in case someone changes the car_loop tables causing a buffer overflow by mistake. This also helps to remove several smatch warnings, with is good.

2014-12-04[media] stv090x: remove export symbol for stv090x_set_gpio()Mauro Carvalho Chehab2-15/+10
Drivers that use dvb_attach can have just one exported symbol, or they will cause compilation breakages depending on the selected frontends. As Jim reported: drivers/built-in.o: In function `technisat_usb2_set_voltage': technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio' make: *** [vmlinux] Error 1 That happens because, on his configuration, the configuration is: CONFIG_DVB_USB=y CONFIG_DVB_STV090x=m Luis proposed ar way to fix, but that would just force the STV090x to be selected, even if one wants to use a device with a different frontend. Instead, let's do the right thing: move set_gpio to the configuration structure and fill it during dvb_attach(). This way, the driver can still call it, and dvb_attach() will load stv090x module only if the device really needs it.
