Subject: [PATCH] EFI loader: remove dead code
Date: Tue, 1 Nov 2016 20:38:08 +0300	[thread overview]
Message-ID: <20161101173808.GA2682@vnote> (raw)

*e820ext is always NULL in 'alloc_e820ext()' (see the code of 'exit_boot()').
Therefore the 'if' condition is always false and the entire 'if' statement is
pointless. Remove it.
