sparc64 / bbc_i2c.c

Hi all

I got bitten by this problem on sparc64 (a blade 1000)

summary :

modprobe bbc

runs kenvctrld which uses 100% of a CPU for 5 seconds,
then 0% for 5 seconds, then 100% .. and so on. The author
cited above suggests removing the line

remove_wait_queue(&bp->wq, &wait);

in the function

static int wait_for_pin(struct bbc_i2c_bus *bp, u8 *status)

Is there a better way?

I can test patches if that would be helpful.
