From b9e8caa7a67535fc544c2504fae3e71a02cfb01a Mon Sep 17 00:00:00 2001 From: Frans Klaver Date: Fri, 16 Jun 2017 19:45:56 +0200 Subject: [PATCH] staging: fusb302: don't bitshift __le16 type The header field in struct pd_message is declared as an __le16 type. The data in the message is supposed to be little endian. This means we don't have to go and shift the individual bytes into position when we're filling the buffer, we can just copy the contents right away. As an added benefit we don't get fishy results on big endian systems anymore.
