driver core: remove drivers/base/sys.c and include/linux/sysdev.h
Now that all users of 'struct sysdev' are removed from the kernel, we can safely remove the .h and .c files for this code, to ensure that no one accidentally starts to use it again. Many thanks for Kay who did all the hard work here on making this happen. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

1/**
2 * System devices follow a slightly different driver model.
3 * They don't need to do dynammic driver binding, can't be probed,
4 * and don't reside on any type of peripheral bus.
5 * So, we represent and treat them a little differently.
6 *
7 * We still have a notion of a driver for a system device, because we still
8 * want to perform basic operations on these devices.
9 *
10 * We also support auxiliary drivers binding to devices of a certain class.
11 *
12 * This allows configurable drivers to register themselves for devices of
13 * a certain type. And, it allows class definitions to reside in generic
14 * code while arch-specific code can register specific drivers.
15 *
16 * Auxiliary drivers registered with a NULL cls are registered as drivers
17 * for all system devices, and get notification calls for each device.
