[PATCH] xHCI: Remove redundant variable in xhci_resume()

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

 



Set hcd->state = HC_STATE_SUSPENDED if there is a power loss during system
resume or the system is hibernated, otherwise leave it be. The variable
old_state is redundant and made an unreachable code path, so remove it.
