checkpatch: trailing statements ensure we report the end of the line
When reporting some complex trailing statements we report only the starting line of the error, that tends to imply the shown line is in error and confuse the reader. As we do know where the actual error is report that line too with an appropriate gap marker where applicable. #ERROR: trailing statements should be on next line #1: FILE: Z202.c:1: + for (pbh = page_buffers(bh->b_page); pbh != bh; + pbh = pbh->b_this_page, key++); #ERROR: trailing statements should be on next line #4: FILE: Z202.c:4: + for (pbh = page_buffers(bh->b_page); [...] + pbh = pbh->b_this_page, key++); Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
