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.
