Subject: igb: Fix PPS input and output using 3rd and 4th SDP
From: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
commit 207ce626add80ddd941f62fc2fe5d77586e0801b upstream.
Fix handling of the tsync interrupt to compare the pin number with
IGB_N_SDP instead of IGB_N_EXTTS/IGB_N_PEROUT and fix the indexing to
the perout array.
Fixes: cf99c1dd7b77 ("igb: move PEROUT and EXTTS isr logic to separate functions")
