Subject: IRDA: cnt is off by 1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb0886745a75ce98bde3aac421adc69fe61a1905;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.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.
