From 3d1e7aa80d1c0e7ce8313f21c1e9c14a12d3ba48 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 21 May 2020 13:05:43 -0500 Subject: misc: rtsx: Use pcie_capability_clear_and_set_word() for PCI_EXP_LNKCTL Instead of using the driver-specific rtsx_pci_update_cfg_byte() to update the PCIe Link Control Register, use pcie_capability_clear_and_set_word() like the rest of the kernel does. This makes it easier to maintain ASPM across the PCI core and drivers. Remove the now-unused rtsx_pci_update_cfg_byte() and ASPM_MASK_NEG definitions. No functional change intended.
