[PATCH] video/aty/mach64_ct.c: fix bogus delay loop
CT based mach64 cards were reported to hang on sparc64 boxes when compiled with gcc-4.1.x and later. Looking at this piece of code, it's no surprise. A critical delay was implemented as an empty for() loop, and gcc 4.0.x and previous did not optimize it away, so we did get a delay. But gcc-4.1.x and later can optimize it away, and we get crashes. Use a real udelay() to fix this. Fix verified on SunBlade100. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
