Inaky Perez-Gonzalez 71f78afd67 wimax: fix kconfig interactions with rfkill and input layers
WiMAX can work without RFKILL, but it was missing a check to make sure
RFKILL is not being made a module with wimax compiled into the
kernel. This caused failed builds in s390, where CONFIG_INPUT is
always off.

When RFKILL is enabled, the code uses the input layer to report
hardware switch changes; thus, if RFKILL is enabled, INPUT has to be
too. It also needs to display some message when INPUT is disabled that
explains why WiMAX is not selectable.

(issues found by Randy Dunlap in the linux-next tree).

# WiMAX LAN device configuration

# Note the ugly 'depends on' on WIMAX: that disallows RFKILL to be a
# module if WIMAX is to be linked in. The WiMAX code is done in such a
# way that it doesn't require and explicit dependency on RFKILL in
# case an embedded system wants to rip it out.
#
# As well, enablement of the RFKILL code means we need the INPUT layer
# support to inject events coming from hw rfkill switches. That
# dependency could be killed if input.h provided appropiate means to
# work when input is disabled.

help
Select to configure support for devices that provide
wireless broadband connectivity using the WiMAX protocol
(IEEE 802.16).
Please note that most of these devices require signing up
for a service plan with a provider.
The different WiMAX drivers can be enabled in the menu entry
Device Drivers > Network device support > WiMAX Wireless
Broadband devices
If unsure, it is safe to select M (module).

default 8
help
Select the maximum debug verbosity level to be compiled into
the WiMAX stack code.
By default, debug messages are disabled at runtime and can
be selectively enabled for different parts of the code using
the sysfs debug-levels file.
If set at zero, this will compile out all the debug code.
It is recommended that it is left at 8.
