[media] rc-main: fix kernel oops after unloading keymap module

When the rc_map table is created the char pointer of the name of the keymap
is copied to the rc_map->name field. However, this pointer points to memory
from the keymap module itself.

Since these keymap modules are not refcounted, that means anyone can call
rmmod to unload that module. Which is not a big deal because the contents of
the map is all copied to rc_map, except for the keymap name.

So after a keymap module is unloaded the name pointer has become stale. Unloading
the rc-core module will now cause a kernel oops in rc_dev_uevent().

The solution is to kstrdup the name so there are no more references to the
keymap module remaining.

Javier Martinez Canillas [Thu, 9 Jun 2016 01:57:35 +0000 (22:57 -0300)]
[media] s5p-mfc: don't print errors on VIDIOC_REQBUFS unsupported mem type

The V4L2 documentation says that applications must call the VIDIOC_REQBUFS
ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is
supported by the driver.

For example GStreamer does this by first calling VIDIOC_REQBUFS with count
zero for all the possible streaming I/O methods and then finally doing the
real VIDIOC_REQBUFS with count N using a known to be supported memory type.

But the driver prints an error on VIDIOC_REQBUFS if the memory type is not
supported which leads to the following errors that can confuse the users:

[  178.704390] vidioc_reqbufs:575: Only V4L2_MEMORY_MMAP is supported

But this breaks existing configurations over kernel upgrade. Those who
