From 30e3ea4c79dd35e97d04546bd39e2468c8ba63ef Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Tue, 20 Oct 2015 15:22:00 +0530 Subject: [PATCH] dfu: dfu_sf: Pass duplicate devstr to parse_dev parse_dev() alters the string pointed by devstr parameter. Due to this subsequent parsing of sf entities will fail, as string pointed by devstr is no longer valid sf dev arguments. Fix this by passing pointer to the copy of the string to parse_dev instead of pointer to the actual devstr.
