I added Kernel GPIO interface for cxd2820r driver. What I understand I 
should select GPIOLIB in order to compile cxd2820r now. I am not sure if 
that problem comes from recent Media Kconfig re-arrangement or not, but 
for some reason I didn't saw it earlier.

What I should put for Kconfig in order to prevent these errors?

config DVB_CXD2820R
	tristate "Sony CXD2820R"
	depends on DVB_CORE && I2C && GPIOLIB
	default m if DVB_FE_CUSTOMISE
	help
	  Say Y when you want to support this frontend.

[crope@localhost linux]$ make silentoldconfig
scripts/kconfig/conf --silentoldconfig Kconfig
