Subject: PM: Simplify kernel/power/Kconfig
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cf4fb80ca3d591cae366ae8364e3c3f7a68bd249;p=openwrt%2Fstaging%2Fblogic.git

PM: Simplify kernel/power/Kconfig

'n' defaults are pretty pointless and actually bogus when used with
prompt-less config options.

The "bool"/"default y" pair with no prompt can be expressed more
compactly using def_bool.

[rjw: Rebased on top of earlier patches modifying this file.]
