From: Colin Ian King <colin.king@canonical.com>

The frame.flags & FLAG_B_FRAME is promoted to a long unsigned because
of the use of the BIT() macro when defining FLAG_B_FRAME and causing a
build warning. Fix this by using the %lu format specifer.

Cleans up warning:
drivers/staging/media/tegra-vde/tegra-vde.c:267:5: warning: format
specifies type 'int' but the argument has type 'unsigned long' [-Wformat]

Compiling for i686 gives:

Should it be %zu?

Same on ARM32. Yes, it should be either %zu or "!!(frame->flags & FLAG_B_FRAME)".
