mainlining shenanigans
52518e513d
I came across a randconfig build failure from one driver that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when built without CONFIG_USB: ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect': ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb' ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb' Upon a closer look, I find that a lot of the other drivers 'select USB' rather than stating 'depends on USB' as is common for most subsystems. I also find that all except one driver have an extra 'depends on RC_CORE' that is already implied by the top-level 'if RC_CORE' check. Clean up both by reducing the dependencies to the required set.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
