Subject: hpwdt: Only BYTE reads/writes to WD Timer port 0x72
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=d08c9a33b4aa6665b0ee3c4d1b57715fa0eae2a2;p=~shefty%2Frdma-dev.git

hpwdt: Only BYTE reads/writes to WD Timer port 0x72

This patch is to correct the use of the iLO port 0x72 usage.
The port 0x72 is a byte size write/read and hpwdt is currently
writing a WORD.
