Subject: ipr: Fix regression when loading firmware
From: Gabriel Krisman Bertazi <krisman@xxxxxxxxxxxxxxxxxx>
commit 21b81716c6bff24cda52dc75588455f879ddbfe9 upstream.
Commit d63c7dd5bcb9 ("ipr: Fix out-of-bounds null overwrite") removed
the end of line handling when storing the update_fw sysfs attribute.
This changed the userpace API because it started refusing writes
terminated by a line feed, which broke the update tools we already have.
This patch re-adds that handling, so both a write terminated by a line
feed or not can make it through with the update.
Fixes: d63c7dd5bcb9 ("ipr: Fix out-of-bounds null overwrite")
