Subject: [PATCH AUTOSEL 4.19 3/9] xhci: Don't require a valid get_quirks() function pointer during xhci setup
From: Mathias Nyman <mathias.nyman@...ux.intel.com>
[ Upstream commit 9b907c91aa94522ae14bf155ce7b9ccb10a0903c ]
Not all platforms drivers need to set up custom quirks during the xhci
generic setup. Allow them to pass NULL as the function pointer when
calling xhci_gen_setup()
