At least on s390, gcc complains about that:
    drivers/media/i2c/saa7115.c: In function 'saa711x_detect_chip.constprop.2':
    drivers/media/i2c/saa7115.c:1647:1: warning: 'saa711x_detect_chip.constprop.2' uses dynamic stack allocation [enabled by default]

While for me the above report seems utterly bogus, as the
compiler should be optimizing saa711x_detect_chip, merging
it with saa711x_detect_chip and changing:
	char chip_ver[size - 1];
to
	char chip_ver[16];

because this function is only called on this code snippet:
	char name[17];
	...
	ident = saa711x_detect_chip(client, id, name, sizeof(name));

It seems that gcc is not optimizing it, at least on s390.

As getting rid of it is easy, let's do it.

(a.k.a. Kconfig bool depending on a tristate considered harmful)
Fix various build errors when CONFIG_USB=m and media USB drivers
are builtin.  In this case, CONFIG_USB_ZR364XX=y,
CONFIG_VIDEO_PVRUSB2=y, and CONFIG_VIDEO_STK1160=y.
This is caused by (from drivers/media/usb/Kconfig):
menuconfig MEDIA_USB_SUPPORT
	bool "Media USB Adapters"
	depends on USB && MEDIA_SUPPORT
	           =m     =y
so MEDIA_USB_SUPPORT=y and all following Kconfig 'source' lines
are included.  By adding an "if USB" guard around most of this file,
the needed dependencies are enforced.

The gm7113c chip is similar to the original saa7113 chip, so I try to
re-use most of the saa7113 specific setup-/configuration registers.
According to the datasheet, the gm7113c chip has not implemented
any register-addresses after 0x1f, so I add a new entry to for the chip
to the saa711x_has_reg function.
The devices I've seen using this chip will fail to get stable video-sync
if these registers are not zeroed:
	R_14_ANAL_ADC_COMPAT_CNTL
	R_15_VGATE_START_FID_CHG
	R_16_VGATE_STOP
	R_17_MISC_VGATE_CONF_AND_MSB
The saa711x_set_v4lstd is updated to send a simpler configuration-table
to avoid setting these registers.
