[PULL 04/13] dump: Remove the section if when calculating the memory off


From: marcandre . lureau
Subject: [PULL 04/13] dump: Remove the section if when calculating the memory offset
Date: Thu, 21 Apr 2022 16:48:26 +0400

From: Janosch Frank <frankja@linux.ibm.com>

When s->shdr_num is 0 we'll add 0 bytes of section headers which is
equivalent to not adding section headers but with the multiplication
we can remove a if/else.
