| |
Currently, the checkpatch throws an error on long macro expressions which is more than one line i.e the opening and the closing bracket pair not being on the same line. This patch gives the dangling backslash the benefit of doubt and allows it to consider the closing paranthesis on the next line as part of the macro expression and doesn't throw an error.
