From 91a5e63e3f9879e5030064a3c0d23c3777c4f4d0 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 2 Nov 2017 13:47:29 +0100 Subject: [PATCH] i2c: sh_mobile: manually "inline" two short functions Those two functions are very short and only called once. The code becomes easier to understand if the code is directly put into the main xfer function.
