Subject: lib/bootconfig: Fix to remove tailing spaces after value
From: Masami Hiramatsu <mhiramat@xxxxxxxxxx>
commit c7af4ecdffe1537ba8aeed0ac12c3326f908df43 upstream.
Fix to remove tailing spaces after value. If there is a space
after value, the bootconfig failed to remove it because it
applies strim() before replacing the delimiter with null.
For example,
foo = var # comment
was parsed as below.
foo="var "
but user will expect
foo="var"
This fixes it by applying strim() after removing the delimiter.
