Subject: usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=543eb12ecd91df324554b8abc8d52e965bd4922b;p=u-boot.git

usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu)

While trying to use the U-Boot xHCI driver on the MIPS Octeon platform,
which is big endian, I noticed that the driver is missing a few endian
conversion calls. This patch adds these missing endian conversion
calls.
