[PATCH] xhci: Bigendian fix for skip_isoc_td() and xhci_check_bandwidth()

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

 



Some small endian problems were added in commits
 834cb0fc4712a3b21c6b8c5cb55bd13607191311 and
 926008c9386dde09b015753b6681c502177baa30 causing Sparse warnings.

Fix skip_isoc_td() to read DMA pointer correctly, and
xhci_check_bandwidth() to read add/drop_flags LE.
