From 96f31530006492b2c753311431acf71df88b0cdd Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 20 Apr 2016 10:36:36 -0700 Subject: [PATCH] staging: comedi: mite: don't expose mite_dma_reset() This function is only called by the mite driver. Remove the inline function from the header and make it static in the driver. Use the function in mite_prep_dma() instead of duplicating the code.
