From d568739f1c21e1768a887ff85611769f782eb64f Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Tue, 21 Jun 2022 11:54:53 +0300 Subject: [PATCH] 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.
