From 8aef7e8f8de2d900da892085edbf14ea35fe6881 Mon Sep 17 00:00:00 2001 From: Harvey Harrison Date: Mon, 22 Sep 2008 14:53:50 -0700 Subject: [PATCH] bq27x00_battery: use unaligned access helper Remove hand-rolled get_unaligned_be16, this points to a possible bug as bq27x00_read does another endian byteswap which sparse notices: drivers/power/bq27x00_battery.c:81:14: warning: cast to restricted __be16 Which should probably be checked.
