bootconfig: Terminate value search if it hits a newline Terminate the value search for a key if it hits a newline and make the value empty. When we pass a bootconfig with an empty value terminated by the newline, like below:: foo = bar = value Current bootconfig interprets it as a single entry:: foo = "bar = value"; The Documentation/admin-guide/bootconfig.rst defines the value itself is terminated by newline: The value has to be terminated by semi-colon (``;``) or newline (``\n``). but it does not define when the value search is terminated. This changes the behavior to be more line-oriented, so that it is clearer in how it works. - The value search of key-value pair will be terminated by a comment or newline. - The value search of an array will continue beyond comments and newlines. Thus, with this update, the above example is interpreted as:: foo = ""; bar = "value"; And the below example will cause a syntax error because "bar" is expected as a key but it has ','. foo = bar, buz According to this change, one wrong example config is updated.
