Jayachandran C. 07042bef45 Fix OF_finddevice error return value in case of FDT. ... According to the open firmware standard, finddevice call has to return a phandle with value of -1 in case of error. This commit is to: - Fix the FDT implementation of this interface (ofw_fdt_finddevice) to return (phandle_t)-1 in case of error, instead of 0 as it does now. - Fix up the callers of OF_finddevice() to compare the return value with -1 instead of 0 to check for errors. - Since phandle_t is unsigned, the return value of OF_finddevice should be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases as well.
