Module Name:    src
Committed By:   skrll
Date:           Sat Dec 18 14:48:14 UTC 2021

Modified Files:
        src/sys/dev/usb: ehci.c

Log Message:
Fix two bugs

i)  EHCI_HCSPARAMS should be read with EREAD4 (and not EOREAD4). Spotted by
    jmcneill

ii) Apply brackets so that ?: vs | operator precedence doesn't give the
    wrong result.
