Subject: IRDA: cnt is off by 1
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=fb0886745a75ce98bde3aac421adc69fe61a1905;p=linux-2.6-omap-h63xx.git

IRDA: cnt is off by 1

If no prior break occurs, cnt reaches 101 after the loop, so we are still able
to change speed when cnt has become 100.
