swiotlb: Mark max_segment with static keyword
Sparse is not happy about max_segment declaration: CHECK kernel/dma/swiotlb.c kernel/dma/swiotlb.c:96:14: warning: symbol 'max_segment' was not declared. Should it be static? Mark it static as suggested. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
