Subject: Fix remaining big endian issue of hfcmulti
X-Git-Tag: v2.6.27-rc2~64^2~1
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b3e0aeeb7e0f89791c4c3bdfd98b36074c5178e6;p=linux-2.6

Fix remaining big endian issue of hfcmulti

The driver was not so bad at big endian at all, only the optimised fifo
read/write functions need a fix, with this fix the driver works on
a pegasus PPC machine.
