Subject: checkpatch: macros: fix statement counting block end detection
From: Andy Whitcroft <apw@xxxxxxxxxxxx>
We are incorrectly counting the lines in a block while accumulating
the trailing lines in a macro statement, leading to false positives.
Fix end of block handling and general counting for negative context lines.
