[PATCH 5/8] eeepc-laptop: clean up control flow in eeepc_acpi_notify

From: Frans Klaver
Date: Wed Oct 22 2014 - 15:14:44 EST


eeepc_acpi_notify increases the indentation level to a whopping four. If
we revise the conditions a bit, we can reduce that to a more soothing
two and satisfy the indentation guidelines in Documentation/CodingStyle.

Remove an unwanted space while we're in the neighbourhood.
