And not only the release function ? Yes, that would be better.

Obviously you did not review your own patch before sending it.

I am very skeptical that calling single_release() out of the blue is the right thing to do. My instinct tells me that single_release() is only meant for callers of single_open(). -- Jean Delvare http://khali.linux-fr.org/wishlist.html -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
