iscsi_ibft: Fix isa_bus_to_virt not working under ARM
The isa_bus_to_virt is only needed under X86 and in fact the code that sets the ibft_phys_addr is only compiled under X86. As such lets just ifdef the code. Reported-by: kernel test robot <lkp@intel.com> Reported-by: Vijayendra Suman <vijayendra.suman@oracle.com> CC: Maurizio Lombardi <mlombard@redhat.com> CC: Mike Rapoport <rppt@kernel.org> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> --- v2: Remove the ibft_phys_addr as it is defined in iscsi_ibft.h
