[PATCH][next] PCI: Fix ternary operator that never returns 0
From: Colin Ian King
Date: Thu Jan 16 2025 - 12:21:47 EST
The left hand size of the ? operator is always true because of the addition
of PCIE_STD_NUM_TLP_HEADERLOG and so dev->eetlp_prefix_max is always being
returned and the 0 is never returned (dead code). Fix this by adding the
required parentheses around the ternary operator.
Fixes: 00048c2d5f11 ("PCI: Add TLP Prefix reading to pcie_read_tlp_log()")
