Subject: IB: Fix display of 4-bit port counters in sysfs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8b9f23b23e080d820e3c0aa5ccd7834c26ebf96;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

IB: Fix display of 4-bit port counters in sysfs

The code to display local_link_integrity_errors and
excessive_buffer_overrun_errors in
/sys/class/infiniband/<hca>/ports/<n>/counters/
uses the wrong shift to extract the 4 bit values.
