Subject: [PATCH] usb: xhci: xhci_bulk_tx: Don't "BUG" when comparing addresses
|
|
|
|
Octeon uses mapped addresses for virtual and physical memory. It's not
|
|
that easy to calculate the resulting addresses here. So let's remove
|
|
this BUG_ON() completely, as it's not really helpful.
|
|
|
|
Please also note, that BUG_ON() is not recommended any more in the Linux
|
|
kernel.
