Subject: [PATCH 20/27] xhci: dbc: Pass dbc pointer to dbc memory init and cleanup functions
Date: Thu, 23 Jul 2020 17:45:23 +0300 [thread overview]
Message-ID: <20200723144530.9992-21-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20200723144530.9992-1-mathias.nyman@linux.intel.com>
Dbc mem_init and mem_cleanup functions used xhci_hcd to get to the device
pointer. The device pointer can be accessed directly from dbc structure,
so pass a pointer to dbc as a parameter instead.
No functional changes
This change helps decoupling xhci and DbC
