X-Git-Tag: firefly_0821_release~3680^2~1977^2~349 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7b6ab33c28980ae26de09654a0d5db6080c76921;p=firefly-linux-kernel-4.4.55.git Staging: ipack: Provide several carrier callbacks. We provide callbacks to: - set/get the clockrate a module is accessed at, - get the error state of a slot, - get/reset the timeout state of a slot.
