From: Jens Taprogge Date: Tue, 11 Sep 2012 11:34:55 +0000 (+0200) Subject: Staging: ipack: Provide several carrier callbacks. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b6ab33c28980ae26de09654a0d5db6080c76921;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.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.
