media: media/radio: set device_caps in struct video_device Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. But this only really works if all drivers use this, so convert all radio drivers in this patch.

[media] Fix 64-bit division fall-out from 64-bit control ranges Commit 0ba2aeb6dab80920edd9cf5b93b1ea4d6913b8f3 increased the internal control ranges to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value control values in a division or modulus operations since not all architectures support those natively. Luckily, in almost all cases it is possible to just cast to 32 bits (the control value is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to use do_div in one function. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

[media] radio: set vfl_dir correctly to fix modulator regression The vfl_dir field should be set to indicate whether a device can receive data, output data or can do both. This is used to let the v4l core know which ioctls should be accepted and which can be refused. Unfortunately, when this field was added the radio modulator drivers were not updated: radio modulators transmit and so vfl_dir should be set to VFL_DIR_TX (or VFL_DIR_M2M in the special case of wl128x). Because of this omission it is not possible to call g/s_modulator for these drivers, which effectively renders them useless. This patch sets the correct vfl_dir value for these drivers, correcting this bug. Thanks to Paul Grinberg for bringing this to my attention.
