[OpenWrt-Devel] [PATCH] Remove MCU requests for SoC platforms

[Luis Correia]

// NOTE: this patch was just sent to linux-wireless and will
eventually make it's way into both the kernel and compat-wireless.
meanwhile it can be added to openwrt in the mac80211 package as
"602-rt2x00-remove-mcu-requests-for-soc.patch"
// end note

The ralink SoC platforms do not have an MCU.
