TTY: snyclinkmp: forever loop in tx_load_dma_buffer()
My main concern here was the line that said: copy_count = min_t(unsigned short,count,SCABUFSIZE); "count" is an unsigned int here so the cast to unsigned short truncates the upper bits. So if count is 0x10000 then copy_count is 0 and the loop never exits. "count" comes from skb->len in hdlcdev_xmit(). The other min_t() changes are just cleanups.
