[media] omap3isp: ispqueue: Fix uninitialized variable compiler warnings

drivers/media/platform/omap3isp/ispqueue.c:399:18: warning: 'pa' may be used uninitialized in this function [-Wuninitialized] This is a false positive but the compiler has no way to know about it, so initialize the variable to 0. drivers/media/platform/omap3isp/ispqueue.c:445:6: warning: 'vm_page_prot' may be used uninitialized in this function [-Wuninitialized] This is a false positive and the compiler should know better. Use uninitialized_var(). Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
