Hello there,

[linux-4.2-rc1/drivers/gpu/drm/i915/intel_csr.c:353]: (warning) Logical conjunction always evaluates to false: EXPR < 524288 && EXPR> 589823.

Source code is

      if (dmc_header->mmioaddr[i] < CSR_MMIO_START_RANGE &&
            dmc_header->mmioaddr[i]> CSR_MMIO_END_RANGE) {

Maybe better code

      if (dmc_header->mmioaddr[i] < CSR_MMIO_START_RANGE ||
            dmc_header->mmioaddr[i]> CSR_MMIO_END_RANGE) {

Regards

David Binderman
