From 55299da8c17f23249497ee8868a5a268c6e3fbcc Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Mon, 7 Feb 2022 16:51:25 +0200 Subject: [PATCH 43/44] PCI: qcom: Define slot capabilities using PCI_EXP_SLTCAP_* The PCIE_CAP_LINK1_VAL macro actually defines slot capabilities. Use PCI_EXP_SLTCAP_* macros to spell its value, and rename it to better describe its meaning.
