irda: buffer overflow in irnet_ctrl_read()
The comments here say that the /* Max event is 61 char */ but in 2003 we
changed the event format and now the max event size is 75. The longest
event is:
"Discovered %08x (%s) behind %08x {hints %02X-%02X}\n",
12345678901 23 456789012 34567890 1 2 3
+8 +21 +8 +2 +2 +1
= 75 characters.
There was a check to return -EOVERFLOW if the user gave us a "count"
value that was less than 64. Raising it to 75 might break backwards
compatability. Instead I removed the check and now it returns a
truncated string if "count" is too low.
