Subject: ieee1394: fix broken signed char assumption.
X-Git-Tag: v2.6.13-rc3~315
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=07bbeaf12310263d808b1958f8413b95f98786ea;p=linux-2.6

ieee1394: fix broken signed char assumption.

"ack_code" is assigned (and tested against) negative numbers, but was
declared as "char".  Which only works if "char" is signed - which it
necessarily isn't.

So make that signedness assumption specific.
