commit b8da302e2955fe4d41eb9d48199242674d77dbe0 upstream.

pci_device_add() calls HEADER fixups after pci_configure_device(), which
configures Max Payload Size.

Convert MPS-related fixups to EARLY fixups so pci_configure_mps() takes
them into account.

xhci: fix unsafe memory usage in xhci tracing 2021-09-12T06:58:28+00:00 Mathias Nyman mathias.nyman@linux.intel.com 2021-08-20T12:34:58+00:00 1234849353b09b40f6c7189641e22e0e2040e91d commit cbf286e8ef8337308c259ff5b9ce2e74d403be5a upstream. Removes static char buffer usage in the following decode functions: xhci_decode_trb() xhci_decode_ptortsc() Caller must provide a buffer to use. In tracing use __get_str() as recommended to pass buffer. Minor chanes are needed in xhci debugfs code as these functions are also used there.
