Subject: [PATCH 01/24] media: pvrusb2: fix DVB_CORE dependency

From: Arnd Bergmann <arnd@...db.de>

Now that DVB_CORE can be a loadable module, pvrusb2 can run into
a link error:

ld.lld: error: undefined symbol: dvb_module_probe
>>> referenced by pvrusb2-devattr.c
>>>               drivers/media/usb/pvrusb2/pvrusb2-devattr.o:(pvr2_lgdt3306a_attach) in archive vmlinux.a
ld.lld: error: undefined symbol: dvb_module_release
>>> referenced by pvrusb2-devattr.c
>>>               drivers/media/usb/pvrusb2/pvrusb2-devattr.o:(pvr2_dual_fe_attach) in archive vmlinux.a

Refine the Kconfig dependencies to avoid this case.
