Re: [PATCH] sx tty_driver add .owner field remove MOD_INC_DEC_USE_COUNT

[Hanna Linder <hannal@us.ibm.com>]

Heh. I figured out why I deleted it, it was not a mistake. The whole
function is commented out! Except the func_enter and exit calls which
are printk wrappers. Besides, no one ever calls this function anyway...

So leave it out. No need to put it back in...
