[PATCH 06/14] xhci: add helper to allocate command with input context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a xhci_alloc_command_with_ctx() helper to get rid of
one of the boolean parameters telling if a context should
be allocated with the command.

No functional changes, improves core readability
