Revert 9b28ef1e4cc0 [ Upstream commit e1b0fa863907 ], it causes regression in 6.12.49 stable, no issues in upstream.
Commit 9b28ef1e4cc0 ("usb: xhci: remove option to change a default ring's TRB cycle bit") introduced a regression in 6.12.49 stable kernel. The original commit was never intended for stable kernels, but was added as a dependency for commit a5c98e8b1398 ("xhci: dbc: Fix full DbC transfer ring after several reconnects").
Since this commit is more of an optimization, revert it and solve the dependecy by modifying one line in xhci_dbc_ring_init(). Specifically, commit a5c98e8b1398 ("xhci: dbc: Fix full DbC transfer ring after several reconnects") moved function call xhci_initialize_ring_info() into a separate function. To resolve the dependency, the arguments for this function call are also reverted.
