Commit 08b3c894e5 "MIPS: lantiq: Disable xbar fpi burst mode" accidentally requested the resources from the pmu address region instead of the xbar registers region, but the check for the returns value of request_mem_region() was wrong. Commit 98ea51cb0c8 "MIPS: Lantiq: Fix another request_mem_region() return code check" fixed the check of the return value of request_mem_region() which made the kernel panics. This patch now makes use of the correct memory region for the cross bar.
