Re: [PATCH] arm: rmobile: Fix off-by-one error in cpuinfo

In rmobile_cpuinfo_idx() there is an off-by-one error in accessing the rmobile_cpuinfo array.

At the end of the loop, i is equal to the array size, i.e. rmobile_cpuinfo[i] accesses one entry past the end of the array. The last entry in the array is a fallback value so the loop should count to ARRAY_SIZE(rmobile_cpuinfo) - 1 instead, this will leave i equal to the index of the fallback value if no match is found.
