From c81c9c3e0fd5170e7bede7d06202062338644e93 Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Mon, 28 Sep 2015 17:18:44 +0200 Subject: [PATCH] staging: most: consolidate code The function drci_rd_reg() always delivers little endian representation of the 16-bit DCI register. The value returned by this function must always be carefully converted from __le16 to u16 type. This patch moves all those conversions to the function itself.
