[media] usbvision: Replace memcpy with struct assignment
This kind of memcpy() is error-prone. Its replacement with a struct
assignment is prefered because it's type-safe and much easier to read.

[media] Improve media Kconfig menu
I've always found it very confusing that the "Media ancillary drivers (tuners,
sensors, i2c, frontends)" comment came after the "Autoselect" option. This patch
moves it up and changes the "Autoselect" text to correspond more closely to
the "Media ancillary drivers" comment.
It also fixes two typos.

When the bttv driver is running without i2c_debug being set, the kernel
log is being flooded with the string ">". This string is really a part of
a debug message that is logged using several substrings protected by a
conditional check.
This patch adds the same conditional check to the leaked substring.

[media] media/rc: fix oops on unloading module rc-core
During modiles initialization rc-core schedules work which calls
request_module() several times to load ir-*-decoder modules, but
it does not wait or cancel this work on module unloading.
rc-core should use request_module_nowait() instead, because it
anyway cannot load modules synchronously or cancel/wait pending
work on unloading, because this leads to deadlock on modules_mutex
between several "modprobe" processes.
